It was possible to take out a loan for BTC in the middle of last year and this would be a good solution. Now it will be as stupid as shooting yourself in the face and thinking that you will miss - the chance is incredibly small, you can say that zero.
And in principle, one of the main rules of trading - do not trade with loan money if you are not sure that you will win. Now there is no certainty about this for sure, because now is really the time to close all your debts and fix your profits, and not try to snatch more.
