It's way too late to make it illegal effectively
Both Terra and I agreed that Bitcoin would be useless if they just block fiat transfers to exchanges, so claiming Bitcoin is somehow invincible to the govt now is hilarious. The fact the govt has NOT blocked these transfers tells you all you need to know, that they seem to support the digital shitcoin scam because they hope to segue it into a cashless society slavery system and hope to distract people away from metals.
For something to function as money or a unit of account, it has to have some type of price stability. Bitcoin is designed to have a financial crisis every four years (the halving) for the rest of your life and is impossible to have any type of stability. It's literally designed from the ground up as a pump and dump scam. This is why people that call it a Ponzi actually do have merit, because money is NOT supposed to be designed that way with retardedly laughable volatility on purpose.
