Bitcoin is no doubt risky investment, but it depends on people, bitcoin is opportunity to some and challenge to some. I think you should not borrow money to buy bitcoin.
Bitcoin is an opportunity that needs to be grabbed and an challenge to work it out.Yes there were risk involved with it but if an investor has its own strategy inorder to profit then he can be responsible in his actions if taking that risk is the path that he is going to take.Borrowing money is not advisable for me because the unstable price of bitcoin can cause panic to anyone who is new in this community.Pretty sure if the money invested does not comes from his owns wallet this might cause stressed to an investor if he can't be able to handle different situations due to price votality.
