Hello There!

At one time, I stopped being interested in the altcoin-markets because of the situation there. Famous projects were dropping their bags off to gullible investors to get even more money.
Do you think the situation has changed in the year 2020?

Is it safe to trade ERC-20 tokens and is it possible to earn something else?
Token ERC20 dominates the number of coins in the cryptocurrency market but we must be aware that most of the ERC20 tokens do not have a clear usecase and do not have a large transaction volume and can even be considered illiquid. Regarding whether there was market manipulation in 2020, I think maybe the conditions will be different because investors have started to have experience in choosing good coins or tokens
