That's right, sometimes even smart people can be fooled just because of their greedy "thing". Many people still lack self-control so they can't think clearly or just do their own research. Even though they do little research is more valuable than having to lose assets due to carelessness.
Losing assets due to carelessness is very ridiculous, especially if that person already has a lot of experience in crypto, it is really unfortunate that this can happen because some smart scammers are still able to fool.
