You should talk to some of the newcomers who got in back in 2017, they too were saying the same thing as you "buy shitcoins, they may go higher than bitcoin". Now most of them are gone because they lost all of their money when those shitcoins that were promising them riches went down 95%.

The fact is that if a coin already exists we know if it is a good coin or a shitcoin. So far out of tens of thousands of cryptocurrencies only bitcoin is a good coin the rest are pump and dumps.
