I learned the hard way that Hodling BTC is the only way. I wanted to grow my BTC so i sold my 1BTC @32K a month ago and put that money in DeFi for yield farming in those high APY. I took some losses and some gains. Now BTC jumped 47K. If i would have just HODL all this way i would have more USDT then if i buy BTC now. Lesson i Learned: Yield farming is useless. People put so much at risk entering smart contract not to mention the daily time waste. Just HODL and you would have more more money than anyone yield farming in long run.
Then, it is about time to learn from your bad and disappointing experience but I'd never think that it was regrettable unless you are selling compared to the buying price.
But just to said that not all holding making huge benefits, they are sometimes at worse or losing a lot. But if we are talking about holding BTC, you have something to expect a better price in the long run which is perfect for a long-term holding.
