Altcoins are not supported by anything and they dont even have any real products that work. Therefore, they will simply die in the coming year. 95 percent
How many altcoins do you expect will die in the coming year? The death of altcoins is the death of crypto, hope you know that.
maybe there is some project that not last long for more years, i guess it still depends on the altcoins itself. Altcoins seems to be good for long term depends on their uses i guess.
