OP may borrow money to invest in bitcoin but does he have a plan to repay the debt if that investment fails? Does he have a stable job and income? Or is he just unemployed and wants to get rich by borrowing money to gamble?
That's a wrong question. OP is planning to borrow money from the bank, do you think bank will agree to lend him money if he does no have the capacity to pay?
The bank will not care whether you can repay the debt or not, they will lend you money if you have assets with a value equivalent to the amount you need to borrow as collateral such as real estate, houses...
First thing first I thank to you all for sharing your opinions with me. If I don't lose the base money then yes I can surely handle the loan's interest. But if I lose like %20-30 then bell of chaos is likely to start ringing.
Also, from what OP said, we can see he is investing with money he can't afford to lose.
We don't know what OP's real situation is but if he doesn't have a plan and can't pay off his debt if his investments fail. Borrowing money to trade on margin is an extremely bad idea.
