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?
If you take a loan it all now depends on the arrangement or policy they made. Wether you pay it with interest no matter how volatile the market is or depends on the $ value (if fiat is still existing).
