Yes. I agree with you. Most altcoins are scams, and scams! Therefore, it is necessary to conduct a thorough analysis of ico projects.
Scams are usually profiting from people that don't read into a project. Reading the project then investing goes far.
A lot of people investing after reading the column "gainers and loosers" on coinmarketcap. To read and research is too difficult, they are here for quick and easy money.
Mostly of people are following others or shillers. Remember when the market has been losing a lot of value from its peak price and then so many new complaints thread about that in here. Because a lot of people consider the crypto as the easiest way to get money, i thought that you have seen there was even a child that has become a millionaire caused by crypto.
