It's always true but it does not mean too much as all shitcoins, scam meme tokens can say similarly like

How many cryptocurrencies have failed?In this section, please don't compare it to other coins, especially shitcoins or memecoins.
This discussion is about Bitcoin and cash. Don't divert from it.
