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.
I think Defis is a good project but compared to bitcoin investment it is risky and bitcoin is less risky because there were just so many investors when it comes to bitcoin. Defi mostly could fail in the process but I see a lot of Defi project gives a good amount of profit especially in just a short term of the investment. Defi is the new ICO here and investing in it was great in my experience but I guess you're just unlucky picking a good Defi token investment. If I have a good volume of bitcoin I will not exchange it for some token but if it was just a small amount I would take a risk since defi would give much more profit.
