to be honest in my opinion avoiding fraudulent projects is very difficult. although we have thoroughly researched the road map, whitepapaer and also the team and its managers. sometimes we also remain deceived because fraudsters always have new ways to cheat and are smart at making projects look good. so I think cryptocurrency prone to scammers is a risk we must accept when investing and working in cryptocurrency.
I disagree, avoiding scams projects is really easy, do not invest in icos or ieos, do not invest in coins with less than two years in the market and do not invest in coins outside the top 20, if you do that then you are protecting yourself of almost all the scam coins in the market, you are going to miss some opportunities to make money but that is better than to lose your money, you need to forget about what other traders are making and concentrate only on the money that you can make with your skills.
