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 general trend, so it has purchased up to 100,000 Bitcoins, and these Bitcoins have brought thousands of times of growth.

Ethereum is another major innovation. If Bitcoin replaces gold, then Ethereum replaces the US dollar. The greatest development of Ethereum is "smart contracts". Ethereum uses technical means to make human property sacred and inviolable. More than ten or twenty years ago, many people in northern Shaanxi bought shares in coal mines. These bastard coal bosses took other people's money and earned hundreds of millions of times the return. People came to them for dividends, and they didn't even return the principal. There are too many such things. Every year, the economic losses caused directly by human integrity issues are as high as trillions! How ridiculous the so-called law is! However, if a "smart contract" is used in a project when financing, the distribution method will be written into the program. When it is time to distribute dividends, the "smart contract" robot will automatically put the money (USDT) into the hands of shareholders, and the most amazing thing is that once the smart contract is generated, even the king of heaven cannot tamper with it. This is the charm of blockchain°! Smart contracts only need to spend a few dozen dollars of Ethereum as fuel!This will ensure that your assets are absolutely safe.
