It has to be said. Its common sense. There are thousands of coins. Scamcoin, losercoin, Shiba coin. All real coins btw.
Yes there will be a couple coins that are very valuable in a couple years but the vast majority of them will be worthless.
Only coins that do things will be valuable. Coins that you have that are just there to hopefully go up on value so you can profit will be worthless.
Its like the dot com boom. You are betting on websites. Which website is going to get the most visitors. Most died.
I think you are right. Many coins will really fail and lose their value. This is due to a number of factors. For example, some of the coins are simply useless and will be quickly thrown away after the creators receive any real assets. Another factor is insufficient funding or launch problems. This is another part of the coins, which seem to be promising, but due to the lack of professionalism of the team and lack of funding, they can simply leave the market. Well, the third factor is that new, more attractive coins with practical application and excellent financing appear on the market, they are crowding out another part of the coins. The strongest wins in this.
