Are cryptos another version of dotcom bubble?

[sturec22]

First of all, the last thing I want to create is a FUD, however I am not feeling so positive these days.
I have been in this market since late 2017. So many people around me have told me that cryptos is the next dot-com bubble.
I have been always trying to keep calm, however the fall that is happening since 6th is making me wanna throw up. - I am also in a long position that's why I am more scared -

Is there any reason why you don't think that this is not a dotcom bubble? I didn't experience the dotcom bubble - I was a child, I only know from what I read -, if there is anyone who directly experienced those times that would be great for us to listen out.
