I bought 3 btc on credit for 19k about. What should I do? I am way underwater.
all you need to do is wait for the increase in price of bitcoin for about 3 to 4 months and bitcoin price will be back to $19k+ per bitcoin, so you shouldn't worry about the deceased bitcoin price, it already always happen in a market that for every seller there is a buyer.
That's why it is a good thing to avoid buying when the price is at its all time high or at its peak. I wonder what's on those people's mind when they buy bitcoins even if the price was an ath but you're right eventually it will recover and op will have an opportunity to sell.
