Re: Best arguments to make your friends understand that altcoins are not good
I think you underestimate how many altcoins exist. 
A few days ago I saw an interesting article by CoinGecko where they show all altcoins that have died in the last years. The number was over 13,000. So these can already be classified as "failed experiments". This number is from January 2024 however, so the real number may be a bit higher.
Altcoins especially these failed altcoins that died are not failed experiments, but they're successful scam attempts from those founders, developers. They are richer by developments and launches of these altcoin projects, but investors failed and lost money.A few days ago I saw an interesting article by CoinGecko where they show all altcoins that have died in the last years.

If there are developments with those failed and died projects, it's good, but most altcoins are not experiment, and nearly no developments, just launch to scam money.
