First, it does seem like it's a form of money. You can trade it for all sorts of things. Some of them directly. Some you make a trade. But it's super liquid; accepted more widely than a lot of country-specific currencies (e.g. I could pay my friends in BTC because they can use BTC, but they're not going to take rubles). To your questions: 1. You can't know how many shares there are going to be for companies. Even if you choose to use some company's stock as a long term store of value, that company will eventually fail at making profit and will issue new shares. 2. If the US banned BTC, it's easy to move overseas with it; memorize the key (not easy, but possible) and just spend the money when you get overseas. Or if you're going to stay in the US, you could just use it the way the dark web already does (not totally clear on how all that works, but clearly it does).
