In crypto, many Altcoin shills are praising "their" Altcoin, but finally the vast majority of them are just useless "shitcoins". I'm not saying that every Altcoin is a shitcoin and I'm also not saying that it's impossible to make money with alts but it's very speculative, much more than just holding BTC.
I've written a topic about it where I've compared investments in BTC vs. Altcoins, you can take a look if you want: Is diversification into different coins really a good advice for Newbies?
