To take a loan from cryptocurrencies would either be impossible or difficult. Bitcoins and all other cryptocurrencies are not centralized, and also the original identity of bitcoin owners are hidden. What happen to someones takes a loan today and dissapears the next day. There will also be uncertainties in terms of the interest rates since Bitcoin is volatile.
All say everything correctly and it would be all interesting to watch the project, which would take on the solution of these problems in the cryptocurrency market. This would definitely bring the entire crypto market to a new level, as well as give the team an opportunity to earn a decent capital. Let's hope that in the near future we will see something like this.
