Fraud is the only reason why I rarely ever invest into new projects. The topic says "not all" new projects but forgets to mention that "most" are bad. This means maybe we do not bat 100% at bad, but we are definitely doing 90% of them bad, and the remaining 10% have plenty of ones that will fail too, which leaves just the ones that will succeed at 1-5% chance at the very best.
I agree that not "all" of them are bad but with fraud being so rampant and easy there is absolutely no way that we could be easily investing into it. That's why we should be focusing a bit more towards known coins, and taking the risk for the new ones is not that easy at all.
We rely on experience, that is why we can tell about this. Yes, OP had missed saying that most are scam projects that make people have no interest in them but rather rejected them. Though sometimes I invested in new projects and my trust is not the same as what I felt with Bitcoin and ETH, I feel like I wasn't safe doing this - doubts is really in my mind but I give it a try for maybe I was wrong with my expectations. But in the overall assessment of these new projects, something to say that 90% of scam is very close to reality.
