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.
They all works, that it didn't work for you doesn't mean it wasn't working. This is just not the time for DEFI, there was a time they were all bubbling and a lot of people who invested in them were making good profit from their investment, but after everything, investing in Bitcoin still remains the best thing you can do, because after everything Bitcoin still grows while most of these altcoins are just for the moment and after they mostly fade. Though there are still some good ones that keeps moving.
There have been a lot of altcoins that are doing really great this year, Dogecoin really pumped hard this year and even a lot of others that did great. It (dogecoin) later started dropping last weekend which made a lot of people to panic. But I have noticed that there are still lots of people who are ready to HODL, because they are believing they will reach the $1 price.
