Who will guarantee the repaymnet of debt?
I guess thats why borrower has to keep collateral in cryptos.
But cryptos are very volatile. If i kept one BTC (worth 19k USD) as collateral in December 2017, and now the price has dropped to 6200 USD. So, will there be a margin that if value drops below that margin, you have to deposit additional collateral? How is everything going to work?
