Whether it is the encryption industry or other investment markets, there will be scams. People always pay the price for their greed. A lot of scam projects in altcoins don't survive more than three months because they scam you out of your money early on. You may make a profit in the early stage, but when you start to be greedy, that is the beginning of their deception. Therefore, the investment project "time" can be used as a criterion for judging.
