I dont know how to predict altcoins or new project tokens which is I don't have time with them, all I know is how to predict Bitcoin and how I trust this coin. People must do diligence before putting investment and don't believe what others say, you should have your own research especially those altcoins that most commonly will fluctuate the price every now and then or manipulating as a fraud of pump and dump group.
This isn't a game but rather than I consider it a sort of gambling, the real fact is, cryptocurrency's price movement is unpredictable no one knows when it will go or any direction, unlike if this is manipulated.
Theres really nothing anyone can do about it, but I think the easiest way the prevent scams and slow them down is to educate people that are new to this.
After all, you've got the answer.
It's all about us and as I said, when it comes to financial matters like investment, we should have our own research and we don't need to rely upon others opinions to avoid misinformations.
