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.
Yeah, We can consider it today as a wrong decision, But what if BTC dumps and your Defi journey were successful? It's about taking chances but it's not bad to try a small amount first and if successful you will not regret it like you are experiencing today. I'm pretty sure that it was not only you who has the same case, There are many people now who regret selling their BTC and put it to other things that they can get profit. I also sold some of my bitcoins in the 28-35k price range but I didn't sell it all, I made a partition in selling and I'm glad that I did it.
