A lot is up in the air as of now, but before making any predictions it is important to keep a few things in mind.
First thing is that present day crypto is aiming to become the money that people use. Which means that the important question to ask would be - ' Will crypto replace fiat money?'.
Second thing would be to remember that stock markets are just a small slice of the bigger pie. Total world debt is in excess of $200 trillion. Amounts in derivatives alone could be anywhere between $500 to $1000 trillion. Total Stock market valuation is $80-$90 trillion.
If crypto were to just receive just 1% of the total combined wealth of the world (on paper) then market cap of the cryptocurrency would be in tens of trillions of dollar.
I would only venture to say that not crypto has the worlds attention, it will now first needs to establish trust. I think the coming decade would be used for making inroads and establishing trust.
