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.
No, I personally haven't tried it. Bitcoin's price is very volatile, it changes from time to time quickly. No one can predict if bitcoin's price will go up or down. And that's what makes it very risky for bitcoin as an investment. As a wise investor, I will never consider borrowing money to use it for investment or trading. I'd rather use my own money that to do it, I think just like what they say, Invest only the money you can afford to lose.
