We've seen 'legit' projects such as Oyster Pearl going down the drain and projects that were assumed as scams turning out legit.
It's definitely becoming more difficult to know which projects are legit now. Since a lot of the time only the person at the very top knows about the impending scam, leaving the others to pick up the pieces.
Exchanges can't really be blamed for listing tokens that turn out to be scams, since most of the time it is practically impossible to know in advance as for all intents and purposes the projects are a success until the scam.
Yea I agree. All investors must do their own research before investing in any tokens.
