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. but nowaday, it's easy for some people to create some fake token/coins now, which mean they also give a chance for scammers to do their action.
Scammers are multiplying each year, they can adopt every updates and developments.
Be very careful as there are scammers who are good hiding from this market, they can easily create tokens that we may think is good
enough or trustable enough but in the long term process once they've already achieve their targets they'll just simply runaway with investors money living the project to die along the way.
