Trading ERC-20 tokens at this time in my opinion is still safe as long as you are not trapped by garbage tokens originating from there, oh yes, some tokens that came from there have been many who have switched and started using other platforms and also some of them make their own mainnet and in my opinion, instead of staying focused on ERC-20 why don't you try the tokens from mainnet that are just circulating? because this is very interesting.
There are thousands of ERC-20 tokens right now and searching for tokens that are suitable for investment would be like looking for a needle in the haystack. In the past, I had invested in several of the ERC-20 tokens, including TMT (Traxia Membership Token), WPPTOKEN, REPME, Mozo Token, and BitScreener. But none of them gave positive returns. IMO, it doesn't matter in which platform the token is being traded. All it matters is the viability and continued development.
