in fact, in my opinion at the moment it is not convenient to do farming instead it is better to sell all the possible altcoins and buy bitcoin the gains are much greater
Why do you think that farming is no longer convenient? I'm serious about educating myself about it because from what I know, the hype is still around and many are still farming from these tokens/swaps.
But I tend to agree about the last suggestion that you've said. If they're no longer the same in the hype and it's not profitable for you anymore to go with sushi, buy bitcoin or if you prefer wbtc which is just also following bitcoin's price, go for what's the best for you.
