Re: The government will shut down Bitcoin, just watch!
Your core points are disputable. I'm taking them out of order.
"What governments can do is make it more difficult to move between fiat and crypto. That means it is important to get your share of crypto today because tomorrow the door may not be open to you."
No, that's not what that means, assuming for the moment that they're going to do that. If they're going to cut the transfer mechanisms between crypto and fiat, then a lot of people who use crypto as an investment are going to sell then. Crypto will be much cheaper for me, as someone who wants to use it as a currency, once the investors get out. It would do me well to wait. In addition, having some crypto if I had to start using it as a currency will do me little good if I'm still being paid in fiat and can't convert them easily. Only if everyone agrees to use crypto would I get a lot of value from it, in which case I will get crypto in my paycheck. Under your system where the government is running a full-on assault on crypto, that seems unlikely.
"Cryptocurrencies are inherently a better store of wealth than any fiat currency. They are even better than precious metals."
On what basis? Current attempts are hideously volatile, which most fiat currencies and precious commodities avoid. They're also a lot harder to spend. Until those things get fixed, crypto is failing at both the store of value and medium of exchange parts. This isn't an intrinsic defect of the system, and I think a more stable cryptocurrency is possible, but that doesn't mean it exists now or that it ever will.
