Buying bitcoins? no. Im not using my fiat to buy bitcoin. Why use fiat if theres a way to earn btc for free. Maybe earning btc just in case of emergency, ill convert it into fiat and use it.
Usually the one who are buying bitcoins has a chance to earn more, well they are doing this if the bitcoin value goes up, their BTC will also increases, then if the BTC goes does that is the time they will convert their BTC to dollar, they earn if their BTC max the value of dollar, traders usually do this too.
