As for Trump's Shitcoin position, I'm sure he has a specific reason.
We know that Bitcoin and Shitcoins will eventually remove and replace our current fiat system. I'm a horrible economist so I do not understand the value and use of a Shitcoin at this time. I do often wonder since I believe in the HODL Model (I totally just made that shit up) that Shitcoins could be used similar to stock in a company?
