Whether it be buying btc or buying equipment to mine btc. Did you ever borrow fiat to make your purchase? I have not. Just curious if anyone ever has.
Never did, though. It's a bad idea to borrow fiat to buy bitcoins now that the market is bullish. It'll be a hard to time pay those people since the man who borrowed might be swimming in deeper and hotter waters because of the price dip of bitcoins nowadays.
