Because the basis of the cryptocurrency industry today is the use of blockchain, and besides in the creation of financial instruments, I do not see any other application, but it is also necessary to arouse greed in people to warm it up, it is she who develops this market today.
I disagree that the crypto market develops greed. If you think so, then the whole business of the world was created by greedy people. Each of us needs money and everyone is looking for a way to earn it. Greedy people in most cases lose their money, and smart investors take profit from profitable investments.
finally scamper like that will not get anything for longterm in case if people not learn from their mistake.
but its impossible they will learn and can avoid scam project like that, unfortunately new people will always come to crypto that why scamer always been there for newbie.
