Taking a loan to invest in Bitcoin may not be a good idea for small-income people if there's no guarantee of paying the loan without any issues but there's power to pay the loan I also don't see anything wrong in a taking loan and investing it in Bitcoin.
It entirely depends on the investor and how would he or she assess his situation because I know there are some people/investors who have done it successfully as long as they have completely done their own research in their selected field of investments or specific coin in the world of cryptocurrency, but it is not really advisable especially for beginners because this is an unknown waters that even the experts are still having a hard time.
well, good or not it all depends on the prospective investor. however, in general, such methods are not recommended. it is said to be too risky, especially if the analysis and strategy for buying bitcoins are not right. this can actually be done when he is really sure he can pay the loan without the bitcoins he bought. the point is, he can repay the loan with his work. however, I think it would be better if it was the last option exercised if he really believed that bitcoin price would increase anytime soon.
