Why is Bitcoin valuable? Because Bitcoin is as scarce as gold. There are only 15 million Bitcoins that can be circulated in the world. Will Bitcoin replace gold? It will definitely, just like oil cars replace horse carriages. It is just a matter of time. If you want to buy gold, you need to spend 10 yuan more per gram than the market price. If you sell it, you have to spend another 10 yuan in handling fees. One buy and one sell, a loss of 20 yuan. What's more, buying and selling gold requires finding a special person, time and distinguishing the authenticity are also costs, while Bitcoin only needs to be clicked on the mouse, and the transaction can be completed in a few seconds on the exchange. Gold also has some disadvantages - it cannot be used to trade small commodities. You can't buy a bottle of milk tea with gold, right? But Bitcoin can do it. Or large transactions require cutting gold, and there is the cost of wear and tear. If you want to do cross-border transactions, use Bitcoin transactions, you can use extremely low costs, do it quickly and safely, and avoid taxes, no one will refuse. The US government has long seen through Bitcoin and knows that this thing is the trend of the times, so it purchased as many as 100,000 Bitcoins. Currently, these Bitcoins have brought thousands of times of increase.
