I agree with this opinion that in 2020 there were many scammers .2017 was the same. We must not despair and continue to work, invest and carefully check projects. !!!!!!!
the amount of scammers will increase year after year. moreover, some projects have a good improvement continously. it's a good progress, though. but, it's easy to create some fake token/coins now, which mean they also give a chance for scammers to do their action.
