The way I think about it is that you should never invest in Bitcoin by taking out a loan. You have taken a loan from the bank and also borrowed money from your uncle and not a small amount of money but a lot of money you are in debt right now.
Do not borrow money to invest in bitcoin or risky assets like crypto. But in OP's case, he didn't mention if he has any other source of income because if he has a good job and stable income then getting an investment loan won't be a problem too big to deal with. In case he doesn't have a good income and depends only on investment, then I will also disagree with OP's decision, it is very risky as there is no guarantee bitcoin will be profitable in the next two years. While we all believe that bitcoin will hit ATH in the future, nothing is certain. Depending on the circumstances of each person, we do not need to be too strict in borrowing money to invest.
