Week 8 [15.05-21.05.2017] – Cryptocurrencies

The history of transacions started with barter. Someone wanted to exchange one type of goods for another. He found a guy who needed his goods nad, coincidentally, had the other type of goods. They agreed and so it begun, the world started to exchange goods. Later on, someone realized there is no need for direct exchange of currencies. That led to creation of money. Firstly, it was gold and silver. Its value was secured because gold and silver were extremely hard to obtain. Few centuries later countries started to create money. Its value was secured by technologies used to print it. Governments were (or they thought... and think they were) the only one to prepare such document, that represents some value. People trust governments to some point, so currencies become way to perform transactions. Nowadays, money is partially physical currencies, and partially entries in databases of banks and credit card providers. What has not changed from dark ages, is that we trust some higher power (government) to maintain value of its currency. Some people try to break government's monpoly for currencies with cryptocurrencies. They believe that there is no need to believe in some organisation, if one can restrict amount of currency that will be generated. Trust of users in self-handling currency environment is all they need. Cryptocurrencies will behave as creator wants them to. There will be no money printing in times of need, there will be no physical carrier. This seem pretty nice. On the other hand cryptocurrencies have some problems, like number of transactions that they can handle per second. As I recall Bitcoin can take as much as 7 per second, while MasterCard (for example) about 4900. Cryptocurrencies might be the future, but they are still in their baby years. Take a look at this TED presentation:
https://www.ted.com/talks/neha_narula_the_future_of_money
and tell me what do you think about this concept? Would you trust cryptocurrencies? Maybe you invest some money in Bitcoin or Litecoin?

I like the idea! I don't have got money in Bitcoin or Litecoin, but I know people who have. It is something new, and that's why people are afraid of it, but I'm not sure if rightly. E-money is secured as well and may be easier to make international transactions when you have got one currency for everyone - it won't lose or gain on value.

Soon there will not be traditional currency. A lot of people pay with paypass card. I remember when paying with mobilephone started. It's still strange for me. I saw it maybe two times. This method doesn't look safe for people.
Electronic payment is convinient for people. But for me risk that someone steals your money is bigger than when you have cash in your wallet. I know that banks have a lot of ways to protect your money but there are people who can break them.
Unknown said…
I especially like the idea that no one can "print" cryptocurrencie. Nowadays we have to trust the government and banks.
Unknown said…
That is true, I think the only way to protect yourself is to keep money on few accounts, just like with "normal" money: we do not keep it all at home.
The idea of using cryptocurrencies instead of traditional money is very interesting. It's hard to imagine that all transactions will be performed this way, but I think it's comparable to concerns about switching from physical money to the digital.
Honestly, the only cryptocurrency, which I know more about than just a name it's Bitcoin. It seems to be unusually profitable investment - recently Bitcoin has tripled(!) its value in 12 months. On the other hand, I don't understand people who invest all of their money in cryptocurrencies. I believe it's important to diversify your ivestments in order to reduce the risk.
Regarding mobile payment systems, I consider them safer than contactless payment cards. Currently almost every new smartphone has a fingerprint sensor which can be used to authorize your transactions, while the latter (payment card) can fall into unauthorised hands and easily be used to carry out payment.
I think that cryptocurrencies could be the future of money. That will be really easy to pay all around the world. For now it is something new and doesn't really fully known, so people have some worries about it, especially about security which can not be fully trusted right now.
Unknown said…
I'm not using cryptocurriencies, I simply don't have appropriate knowledge about them yet, so right now I don't trust that kind of payment. However, I'm pretty sure that they are the future as long as they won't be the only way of people's investments.

Did you know that even before gold or silver cocoa beans had been a currency? Originally, it took place in Aztec and Olmec civilization.
Unknown said…
That is true. There are even apps for phone, avialable in app markets that are able to intercept card data using NFC.
Unknown said…
Wise words. There is no perfect solution for securing income.
Unknown said…
Oh yes, the idea of one currency respected all around the globe seems really nice.
Unknown said…
Yes, ive heard about this. Anything hard to obtain can be currency. Some cultures used gold. Nowadays people need to use cryptography to make virtual money hard to obtain.

When I think about Cryptocurrency I can see a lot of advantages:
1) Fraud: Cryptocurerncies are digital and cannot be counterfeited or reversed arbitrarily by the sender, as with credit card charge-backs.

2) Identity Theft: When you give your credit card to a merchant, you give him or her access to your full credit line, even if the transaction is for a small amount. Credit cards operate on a “pull” basis, where the store initiates the payment and pulls the designated amount from your account. Cryptocurrency use a “push” mechanism that allows the cryptocurrency holder to send exactly what he or she wants to the merchant or recipient with no further information

3) Immediate Settlement: Purchasing real property typically involves a number of third parties (Lawyers, Notary), delays, and payment of fees. In many ways, the bitcoin/cryptocurency blockchain is like a “large property rights database,” says Gallippi. Bitcoin contracts can be designed and enforced to eliminate or add third party approvals, reference external facts, or be completed at a future date or time for a fraction of the expense and time required to complete traditional asset transfers.

4) Access to Everyone: There are approximately 2.2 billion individuals with access to the Internet or mobile phones who don’t currently have access to traditional exchange systems. These individuals are primed for the Crytocurrency market. Kenya’s M-PESA system, a mobile phone-based money transfer and micros financing service recently announced a bitcoin device, with one in three Kenyans now owning a bitcoin wallet. (Let me repeat that again. 1/3)

5) Lower Fees: There aren’t usually transaction fees for cryptocurrency exchanges because the miners are compensated by the network (Side note: This is the case for now). Even though there’s no bitcoin/cryptocurrency transaction fee, many expect that most users will engage a third-party service, such as Coinbase, creating and maintaining their own bitcoin wallets. These services act like Paypal does for cash or credit card users, providing the online exchange system for bitcoin, and as such, they’re likely to charge fees. It’s interesting to note that Paypal does not accept or transfer bitcoins.

Very informative comment. Thanks.

I like the idea of free currency. Big banks and governments do not I imagine. Why? Because they would have no control over it. And, in my opinion, that's why it will be pushed back or at least there will be resistance. I've heard about a bank which suspended someone's account beacuse it was used to buy bitcoins. Oh well.
Unknown said…
Yeah, it is hard to imagine that banks would be supporting cryptocyrrencies development.
Unknown said…
I think I could trust in cryptocurrencies, because practically I don't use traditional money, mostly I pay with a card or do online transfers, so maybe bitcoins are good idea. I know some people who use it, but earlier I wasn't interested in the subject. However, I think that today the introduction of these cryptocurrencies for general use will be heavy, this would require many agreements.
I think it is a good idea! To have only one currency all around the world it would be so convenient and easy to use. I think people don't want to use it or don't trust it because it's something new, but maybe it's worth to give it a try. I would rather want to try. I usually pay by card or via the Internet transfers.
I think that the idea of cryptocurrency is very relevant and wonderful. I think that people increasingly like "transparency" as you can see every transaction , and that's great , because it eliminates the many ways fraud. I also remember those years when only there was only Bitcoin and many of my friends began to "mine" them , build the idea that money obtained from the air was great. I think that's because bitcoin became popular. But the coin has always 2 sides. For example, the same bitcoin as it gives anonimnosti began to ispolzuetsa on the black market for selling drugs and weapons, or was the main currency for ransomware viruses.

I believe that cryptocurrencies and technology behind them, blockchain are making a breakthrough in the today's financial world. Bitcoin, as the most popular blockchain-based cryptocurrency has a lot of advantages, for example independency from governments - I see this as the biggest advantage because governments shouldn't control currencies, governments can fail or make bad decisions influencing the exchange rate. Of course there're some disadvantages like the time of transaction, size of the blockchain file and the current situation with using bitcoin for investments instead of transactions, which causes speculators defining it's exchange rate.

Of course like anyone who remembers a time when bitcoin had an exchange rate of $1 I regret not spending a few hundreds on purchasing it:) But it's nearly impossible to foresee things like these.
Unknown said…
Especially that blockchain cannot process as much transactions as for example Visa system.
Unknown said…
Also transparency and full history has some drawbacks: informatorom about transactions Has to reach all coins, and on few years average bitcoin wallet might weight few GB
Unknown said…
Damian, I can agree with you. There are many advantages, but there's not only the positive side of it. We should remember about disadvantages.

Firstly, Bitcoin is able to support illegal activity. According to Mercedes Kelley Tunstall of Ballard Spahr LLP, "Bitcoin has built its reputation and structured its virtual currency around being both anti-government and anti-establishment." That's why it is believed that it can be used anonymously for illegal or antisocial acts. If you scroll over offers in deep web (especially illegal categories), you can see that it's true. It's very often that something illegal is sold for bitcoins.

Secondly, I heard that there's high risk of loss. I don't know much about it, so I won't try 'to be an expert', but I just want to say that there are also disadvantages which we should remember about.

Personally I have almost none knowledge about virtual currency. I don't use it and I don't know if I ever will. Of course I know some people who use it.
Many people still have no trust to things in the Internet and don't even use their bank services via Internet so I think it will take a long time for people to use it in everyday use.
Bartosz Łyżwa said…
I've never used cryptcurrencies like Bitcoin or Litecoin. I have no any opinion about this subject but I think we are using cryptocurrency everyday because we're paying with card. Maybe I'm wrong but personally I think it's a substitute of subtitute etc. At first there was a gold, then the substitute of gold was a coin. Next step was replacing coin by "paper cash" and now we have credit cards with e-money. So what for we should use a substitue of e-money. I have only one purpose - one currency for every country :)
I don’t have any money in cryptocurrencies, but some of my friends use it. I think that they might be the “money of the future”. I rarely use traditional money, I pay for almost everything with my debit card, and I get slightly annoyed when I have to use traditional money. Using digital money is much faster and convenient than searching your pockets for some change.
Vyvyan said…
Cryptocurrencies like Bitcoin might work but it needs time and people have to understand that it's not that different from using credit cards. Would i trust it? Yes i would. And i regret not investing in it when it was created because right now it's very expensive.
I never used cryptocurrencies. I have heard many information about it used by blackmarket because of the anonymity layer that it provides. Maybe one day I will start using it, but for now it's not a regular currency in Poland.
Wojtek Kania said…
I really like the idea of cryptocurrencies. I use bitcoins and it's great and better alternative for traditional bank transfers. For me the main proof that bitcoins and blockchains technology is amazing idea is banks are invest in blockchains. The Bank of England has paired up with artificial intelligence and blockchain specialists in a bid to keep up to date with the fast-growing financial technology sector. (http://www.telegraph.co.uk/business/2017/03/17/bank-england-trials-artificial-intelligence-blockchain-bid-stay/). I really like bitcoins for fast transactions, simplicity and most important thing anonymous. I hope that I will be able to pay in BTC in every shop and it will be very simply like paying by paypass.
Magdalena Popek said…
My knowledge concerning cryptocurrencies is minimal. I wouldn't want to have money I can't see (if I have money on my account I can withdraw it, that's what I mean by "seing it"). Even though I know some people using it, I'm not sure if I want to.
Taking into account banks have no control over cryptocurrencies, they will try to decrease their popularity.
Michał Pycek said…
A friend of mine has invested in Bitcoin and it has been going well for him, however I am not convinced of being so sure about its value and potential perspectives in the future. I think the genuine idea is great and independent, however it may take lots of time for more people to actually switch to it.
I like the idea, but I don't have any bit or lite-coins, mostly because their exchange rate is so unstable for much time they can be worth a lot of money and than in one day their rate can fall by hundreds of dollars. I see them as a substitute for real money in future, but that will be hard to achieve, because real currencies exchange is a business itself, so many countries etc. wouldn't want to change that. I like that cryptocurrencies are giving us a kind of anonymity when we are doing transactions, because when we are using normal debit or credit cards, number of information we are giving to companies is pretty big.
In my opinion, cryptocurrencies is an intresting idea. I sometimes read article about bitcoin and it sounds very great. I'm going to try it in the nearest future.
Unknown said…
I have never used any e-currencies and I don't have much knowledge of them. It sounds great to use one currency all over the world, it would be definitely comfortable way to make transactions. It has always been a problem of exchanging currency and the internet ones can solve them all, but of course it would be hard to introduce them.
Unknown said…
I think we need a little bit more time to get used to the cryptocurrencies and believe in them. People have to have a trust to a place where they store their money and I don't think we have trust in Bitcoins because it associates with black markets.
For now, I don't see why should I change a regular currency to a cryptocurrencies, but some day I'll explore this topic deeper and maybe decide to store some money there.
KamilG said…
For several reasons I am not inclined to believe in the success of the cryptocurrency.
The main reason is security.
Bitcoin is constructed on this way that in order to keep your money safe you need to create your virtual wallet.
However it is protected by a suitable cipher, this does not preclude hackers.
By using service platforms, where wallet access is required, this wallet can be hacked easily.
Another problem is limited availability.
Not every store offers currency payment, and once the choice is limited to popular brands.
Despite the above mentioned disadvantages I find cryptocurrency worth to use. Although accessibility and security are far away from my expectations, I believe that this problem will be solved before long by creating new solutions, algorithms, ideas.
Unknown said…
I think cash in internet and every transaction will be do in Internet so Cryptocurrencies is very important think to hold our security in high level and to feel safe when you do transaction in Internet. I have never use internet currency like bitcoin but in a short future i think most people will use currency from internet.

I don’t have enough knowledge in that field but I think it could be work. The idea is very interesting. People are scared when it comes to trust someone who keep control on their money. That’s why in the past it was the role of the government to care of. It seems to me that we have to grown up to such technology. This is a great responsibility that can completely change our point of view and our habits.

I heard about bitcoin recently, also about how it's value reached 7000$. At this point it sounds a bit like playing on the stock market, you buy bitconis a bit like you would buy shares and it's value constantly chances. What I find absolutely fascinating is mining them, I have zero idea how that even works.
I've heard about cryptocurrencies a lot but never used it. I don't feel it is a good way to locate your savings. It is not stable enough. On the other hand it might be future money, who knows...

I've heard that cryptocurrencies are main currency in darkweb, even for illegal stuff like hitman or drugs.

Maybe in the near future I will try Bitcoin for some small online shopping.

Week 11 [03-09.06.2019] The problem with ecological cars emission in UK

The problem with ecological cars emission in UK Since the adoption of the European Emission Allowance Directive in the European Parliament, all car makers have tried to submit. Since 1992, the Euro I standard has been in force, which limited the emission of carbon monoxide to the atmosphere. The Euro VI standard currently applies, which limits the series of exhaust gases. These include: hydrocarbons, nitrogen and carbon oxides, and dust.   The most significant change was brought by the Euro IV standard. For the first time it introduced the limitation of nitrogen oxides, which are responsible for the harmful compounds of smog.   What is smog?   Smog consists of sulfur oxides, nitrogen and carbon. In addition, solid substances such as suspended dust (PM). Dust suspend in atmospheric aerosols may be in liquid and solid form. These can be particles of sea salt, clouds from the Sahara and artificial compounds made by people. These compounds often come fr

Week 12 (12.01-18.01.15) Are you an early bird or a night owl ?

Owls are nocturnal creatures. They’re wide awake at night and they sleep during the day. If this sounds like bliss to you, then, like about 20 percent of the population who find themselves most active at around 9 pm, you may fall into the same category as our feathered friend. Night owls often have difficulty waking up in the morning, and like to be up late at night.  Studies of animal behaviour indicate that being a night owl may actually be built into some people’s genes. This would explain why those late-to-bed, late-to-rise people find it so difficult to change their behaviour. The trouble for night owls is that they just have to be at places such as work and school far too early. This is when the alarm clock becomes the night owl’s most important survival tool. Experts say that one way for a night owl to beat their dependence on their alarm clocks is to sleep with the curtains open. The Theory is that if they do so, the morning sunlight will awaken them gently and naturally.
