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.
You stated enough fact which is of course true, and the funny thing which is also true is that, a lot are getting worthless already without even lasting for a year, this is already seen on coinmarketcap as well as in personal wallets. The truth has to be said and you did it correctly, it is now left for anyone to chose what works for him.
Talking about what works, many people of course made gains from the numerous shitcoins which pumped, and where many gained a lot of people also lost.
The worst part of the whole scenario is that, many are also holding most shitcoins with a long term view, without knowing that, they might not even last and as well, the current market conditions has dealt with a lot of them. So in all sincerity, let's learn to hold good coins for long term, coins whose team are committed to their long term goals, through this way, we can be assured we are on the right path.
