Many crypto projects have excessive false claims to provide investors with maximum profits, and greedy people are always baited and scammed. Over time scam projects will slowly reveal their true colors, they are just trying to deceive investors.
So learn to analyze crypto projects and don't believe in any promise of high profits.
Well, the truth is that some people had learn from their mistakes but some still accumulating these shitcoins. That is why we could see that still a lot of people get scammed and the number of scam projects is also growing. If we all just know how to assess the project or even just be cautious in investing in projects who promise huge returns (APY), I could say that they will be getting out of their numbers and turning to zero in the future. But I'm not sure how we could change this situation knowing that there are a lot of greedy people that are still looking for instant money and quick-rich.
And this is one of the most important reasons why those projects refuse to disappear, anyone that has been in this market for long enough should be able to recognize that all of those projects are scams, however since the possibility still exist of making some money despite this fact many traders decide to ignore this as their greed takes over them and it becomes impossible for them to resist such offer, but once they lose money then they come to the forum to complain about it, as if they knew nothing about the project being a scam.
These scam developers can always repeat their scamming process as they can introduce it anonymously.
I remember, a lot of pump and dump masternode coins that were introduced via discord channel.
Discord itself is not a scam, but scammers used this channel to sell their masternode coins.
And most of these MN coins become dead few months after they hit the trading market.
Leaving most of the MN owners not getting even their initial investments.
So yes, people should be aware of these scammers, because they are still here, waiting for their next victim.
