i think altcoin will have a bright future, but not all of them, in fact, most of them will disappear in two or three years, only which proven by times will success and do a favor to blockchain
Yes we have a more than 100 altcoins in the market, and daily new coins are coming to the market in that only a few coins will stand for a long time rest of all will disappear after collecting money from investors. So anytime you are going to invest in altcoins prefer first 20 coins and check the history of the coin when they came and how's their project is going on after verifying everything you can invest your money.
I think of the many altcoins that keep coming each time it proves that the need for altcoin continues to increase, even if some are dead, disappeared or scam, but keep coming altcoin this means every dev get big funds from investors means there are many investors who are in cryptocurrency right ? and will always increase, altcoin has a beautiful future i think
