Bitcoin was designed after the 2008 economic crisis. It is deflationary. The halving of output every four years will further reduce the supply of Bitcoin. The imbalance between supply and demand will further push up the price.
A Bitcoin ban is out of the question, and the death of the dollar is inevitable. What Bitcoin offers is an alternative when the market crashes.
Many people don't even conceive the idea of a world without the USD as the global reserve currency.
But over decades the global reserve currency has been changing, from the Spanish Real to the British Pound, and then to the USD.
Soon the time will come for Bitcoin when it takes over that. We're in the process of this happening right in front of our eyes.
But one thing you can't even conceive is that all those world reserve coins were created by one great power. In the past, Spain or England used to be the dominant empires in the world and are gradually replaced by the US to this day, which means that whichever country is the most powerful will dominate the world's currency.
In contrast, bitcoin is a decentralized and community-backed currency and the community is controlled by the government, so bitcoin is very unlikely to become a global currency. Bitcoin can only be an alternative used in tandem with the current currency, and it is a success.
