To take a loan to invest in a volatile asset is just like gambling which is always two sides. So you have to check what happens if the price drops and stays down there for long while your loan repayment time fast approach, you will be in the risk of losing your collateral and that is usually higher than the loan itself. So you have to check your repayment source even if you want to take such loan but to depend on the bitcoin investment profit to repay the loan debt, is just as good as gambling.

But at the moment, to take such risk is not worth it because the price of bitcoin has been on support and struggling up and down, meaning the volatility is reducing and anytime soon the bear might take over. Therefore, to invest in bitcoin is better at the bottom not from top.
