I don't know who will be that careless with their hard earned money as to donate to him. To even start with, I don't know what will make someone risk such a huge sum of money on trading.
I do not see anything wrong to use such huge amount of money to trade bitcoin but maybe we are still on the same page because he should not use such high leverage. He made big wrong moves.
The market is always the master. The earlier everyone learns this, the better for us.
I think he is not a good trader. Bitcoin has increased significantly and get to all-time high and he then use a leverage of about 20x on a long position at such high price. He should expect at least retracement to at least $100000 again. I will say he gambled with the money.
