I think it is better to hold bitcoin now because the price is extremely low right now. Don't let yourself influenced by other unless yo agree with them.
I wouldn't say that's one of the best suggestions, rather hold on to USDT knowing that you have a chance of buying more bitcoin values if the BTC value goes down. I will rather buy some of the altcoins which declined extremely bad and sell once the market picks up, most altcoins tend to follow bitcoin. You might make so much profit by just doing that
