I noticed some coins are removing from the coinmarketcap and some from specific exchange. I don't understand how the coin vanishing.Could anyone give me some reasons why coins are removing?
These are the scam altcoin, or dead. If the altcoin is removed from the exchange it will soon be removed on the coinmarket. Because coinmarket updates data from all exchanges and you don't have to worry about those altcoins, because it has no future or value
