Even Beanie Babies still exist, they just aren't worth much.
So where do you see "crypto," to the extent that can be a monolithic term, in 10 years? 20? 50? I'll hazard some serious, but somewhat intentionally cheeky, predictions:
10: ETH has overtaken BTC, accounts for most of the market cap in crypto. Like IE 5.5.
20: Difficulty here, I want to say I imagine it is all gone entirely in favor of ... something else. There is a great exodus of money from crypto to that "something else" over a period of 5-7 years. Lots of stories about how "BTC has a market cap of just $1m now, at its peak it was $1t" etc.
50: LaserDisc era. There are enthusiasts still MLMing coins to each other. Most weren't alive during the BTC heyday and are essentially larping.
Possibly. It may not be ETH (It's very likely), but BTC will be overtaken by market cap.
All I will say is that in 10 years time, this industry will slowly but surely be regulated, and tons of useless shitcoins, memecoins, etc will wither away.
