HODL is common practice with many Bitcoiners but has anyone braved the risk of changing out BTC for a stablecoin to then change back into BTC when the price has significantly lowered to gain percentages?...
This is exactly what trading is for, which allows you to sell coins that have reached a high and then buy at a lower price. But to make a profit, you need to be able to trade, otherwise the opposite will happen: you will buy at a high price, in order to sell at a low price later)
