i have a counter question to this * why you want to do this when bitcoin is high instead of doing it when bitcoin is cheap ? thats how you end up buying high and selling low
Here, in principle, the question is whether it is worth taking it at all, since this carries a high risk of losing it. As for your question, I can assume that maybe the OP wants to open a short position and make a profit on the BTC drop.
Maybe it would be okay for him to take a loan if he bought bitcoin now because the price of bitcoin has dropped a bit. Because we are still in its retracement in the market.
Now, if that was the intention of what op did to buy short and take profit immediately, he probably already made a profit recently.
And it is possible that now he bought back again and then held for a moment again at the right time to sell again. So I think this op, has another source of income that is why he was loaned
such an amount, in short he is really capable of paying.
