Today, knowing both worlds, it is the only currency that I trust, it is the only system that I trust and I will dedicate my life to carry this forward. Bitcoin forever.
But you're still need to use fiat because you can't use Bitcoin to pay anything in your country, so you're still trusting fiat even you're not use it as to store your wealth. We might see a big change when CBDC has been launched by the government, it's either they will ban Bitcoin or they still consider to accept it. But you can still use Bitcoin since there's a way to trade Bitcoin without need a permission from centralized entity, as long as you not make any mistake.
True. I hate it when some people say that you only need Bitcoin and they don't think that we can live in different countries. I just can't use Bitcoin where I live, I can buy some things online, but I can't pay rent or buy groceries with it, and I don't think it will be possible any time soon.
