i am new in crypto world and i don't have much information about altcoins and gem hidden coins can any one tell me the difference between altcoins and gem coins and how can i find the real coin for investment?
Understanding Altcoins is an alternative to bitcoin, while gem coins are terms that have quality and profitable coins to invest now or in the future, if you want to see all the coins you can visit coinmarketcap.com, there is a list of thousands of coins there, if you want to try investing , then my suggestion is to choose the top 10 coins now
