I wonder this: if the usual banking system will disappear as such, then she will leave and credit system, leasing and installment payment, debt, etc. As there is no centralized authority that can issue and track correctness of performance. To some extent, this is certainly good, but in fact people who can not immediately earn a large amount of money and will remain in the lower levels of life, which gives the modern banking system (though not ideal). What do you think about this? How to Take a loan in cryptocurrency?
Yeah it is better than credit or even paypal i guess for it will just create a good and cheaper transaction fee. This is why that getting a good system like cryptocurrency will make other system look bad so this one is an example that having cryptocurrency system will take other people to turn away their heads on credits.
In General, it would be good to invent a system similar to paypal only with a focus on cryptocurrencies. Or what would paypal itself introduced the use of cryptocurrency bitcoin in its system.
