how will they crack down on it?
They will use their puppets like Elon Musk to crash the price, they will incentivize moving people over to FED Coins and harm them for sticking with decentralized coins like DOGE that the institutions pumped up just to crash. See the .dot com bubble when this exact thing happened and when the dust settled it was the big players that were left standing and all the little .coms went bye bye due to market forces and consolidation of the internet by the giants that emerged, same thing will happen when crypto goes mainstream. IMO, and I have been wrong before.
