It really sucks to see something like this happening, and I know it's kinda late but I hope that lenders will rethink (or at least stricten) their policy of giving no collateral loans, especially not for longer period of time. It might not be fair to those that are regularly repaying their loans but as we can see even DT1 accounts with decent loan history are not immune to something like this.
They might have every intention of paying it back but if they're unable to or the price rises significantly then it's all too easy to just disappear as there's probably little to no real world ramifications and the only damage done to them is a ruined account.
That might become big issue as we are into bull market now, so if you take a loan and in a couple of months btc goes up 2-3x you might have serious issues with repaying since majority of us still get out of paycheck in fiat. Unless you are part of CM or some other campaign that has fixed btc payrate but even then it's not very smart to think of it as a sure money.
