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...
There are many coins that comes to crypto world now. But not all coins are valuable. Most of the coins were shitcoins. Especially, those that are from airdrops. Coins has no value.
