About the bank stuff, NEVER ask for loans to buy cryptocurrencies, they are simply too volatile, and also, don't lie when asking for a loan on a bank telling you will be using it for something else, when you plan on using it on cryptocurrencies, it is not worth it.
Whem you want to invest, just make sure that the money you are using is not from loan, because it's never be safe, we all know that crypto is very risky and anytime you can lose your money. So think twice before making a loan for crypto.
