Not only that, Bitcoin and the crypto market have opened a completely new technology door, which is blockchain, a technology that I think will dominate the world in the future. Any field in the future will also use blockchain as its backbone database. Besides, Bitcoin can be seen as a new value storage asset class besides gold.
I don't dare think about Bitcoin becoming a global currency. This is quite complicated and with an unstable world like today, it is very unlikely that this will happen. I can only predict that Bitcoin will be a valuable asset that any country will want to have in its treasury in the future.
You're right, I really like your vision of bitcoin. Although it is not easy for bitcoin to achieve success and be compared with gold, or become an asset that any country wants to own. But bitcoin is the only asset that has the potential to do that and I hope it comes true.
I knew Satoshi created bitcoin as a peer-to-peer currency, but I never thought it could become a global currency, that was too vague and had almost no chance of becoming a reality. This world is greatly influenced by centralized forces and that is the government, and they will not easily let things that they cannot control spread without consulting them. For bitcoin to become a currency, it needs their permission and I think that is nothing less than an impossible task. Just because we want bitcoin to be a currency doesn't mean it will definitely become a currency, our world just doesn't work that way.
