Many investors in a certain project doesn't indicate it is a good project. I've saw many projects that they accumulated millions of dollars but in the end they disappear suddenly leaving their investors in a big disappointment. Cryptocurrency is now booming and scams are growing as well. Best thing to do is only invest on those who are really popular and in the top spot of coinmarketcap like eth, ltc, eos, xrp and so on. That will guarantee you a good profit for long term as they have real use-case for their projects.
