Why is investing in crypto looked down upon?

This is speaking from my own experience but I have this feeling that everyone outside of the crypto space looks down upon investors of crypto and on cryptocurrency itself. I haven't told my family about me investmenting in crypto and I will probably keep it this way for a long time but when i'm talking to friends or other people that aren't familiar with crypto, then I have this strong feeling that they think it's something stupid that only idiots would spend their time and money on.

Do you guys feel the same way as me? I really believe that crypto is destined to play a huge deal in the future. Did the same happen when the internet first started appearing?

Sorry for rambling on but this was on my mind lately after having a conversation with someone that kinda made fun of me for believing in crypto and investing in it, instead of investing in something "real" like stocks or bonds.
