Cryptocurrency Cannon - What's Up With That?

i have a lot of sympathy for someone that i met through ipo, because he's like just sold his company. Has only heard shitcoin er narratives about bit coin. Thinks going to get shut down by governments because of the environment stuff. A is cansian, so he believes that money can't be deflationary. Thinks that the supply of money must expand to match gDP growth and and population growth.
