For most Altcoins, there is no future. They just copy and copy some code and then change the name to the new one. These altcoins have no use and value. They are only born for the scam. Of course, there are a few altcoins that are really serious and promising, but the number of such altcoins is very small.
Of course, 99.9% of all projects are doomed. Not because they are all bad. Just go new, more advanced, which perform more functions. or old ones are being improved and new ones are not necessary. Nobody goes on carts now when the plane was invented. There will be ten to twenty narrowly focused altcoins.
