People only own shitcoins to change them for bitcoin later
one day you might wakeup and all shitcoins went down and bitcoin went up
It is silly of you to assume that I own shitcoins. Not every altcoin is a shitcoin, and further, I am not talking about the majority of coins that I invest to HODL, but here I am obviously referring to a portion of my portfolio that I am day trading if you have understood what I was explaining. I can convert everything back to ETH anytime.
Also this supports what I am saying.
