Hello, I am new in this forum but not new in cryptocurrencies, I started trading cryptocurrency in 2016 and my first cryptocurrency I bought that time is vergecurrency and other penny coin. And I returned my money in bundle because they have good tech and very good team..So early this year I noticed that a lot of coin is now scam and failed promises. So please if you want to buy any coin don't go to coinmarketcap only because coinmarketcap can list any coin without verifying it well, just go to their telegram group and ask questions I think this can help you stay away from scam coin...
You are right, there are many coins in unverified markets are in the market trophy. This makes the situation so bad, there are many people who wonder about it because they do not want to lose their profits. even now it's all hard to predict. then we must be careful.
