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.
DeFi is a good and attractive topic and direction nowadays, but it's risky features nobody's cancelled. Of course our experience is a very valuable thing for all times and it is a pity that very often we get our experience through losses and regrets. And of course it is absolutely useless to say now you should better invest into DeFi assets from some other resource, not touching assets in BTC. But nowadays the step was done and result will not change. DeFi is really attractive, but nowadays it is a hype direction. And it will not last forever in my opinion. But holding Bitcoin is quite another thing.
