For me it's not advisable to borrow fiat money just to invest in bitcoin or in any alts and ico. The risk in investing here is very high and you can't know for sure when you are going to profit or if you're going to profit at all. Borrowing fiat means you need to return what you borrowed in a certain time, what your deadline comes and you're not still profiting in your investment? Only invest what you can afford to lose.
