I did not borrowed fiat to buy bitcoin , Since bitcoin and other crypto currencies volatile in crypto market ,you cannot predict what will happen rise or fall. Best is to buy bitcoins when price value is less ,and when bitcoin price rises and when your requirement met you can sell it. Another best part is earn bitcoins instead of borrowing fiat and cryto currencies.
Actually, I am excited about bitcoin very much, Ive never borrow fiat to buy such any coins .Because for me ,bitcoin is such an extra work, I know how much risky in this crypto currencies, so I think that its so stupid if I borrow someone fiat to buy bitcoin. In fact, with digital market you and me dont know exactly whether the price will go up or fall, its really mysterious. It fluctuates regularly ,hence, I choose the safe way to do with it. Maybe I wont get a big benefits, but I have chance to get a little as long as I can learn more about this market.
