And why it's impossible to copy bitcoin's proof of work, meaning that only bitcoin's proof of work is valid:
To say that bitcoin’s mechanism is the only valid one is wrong. There are other coins that are built on pow mechanism but just with different algorithms. It doesn’t mean theirs are automatically invalid.
If many people wanted to buy another PoW coin instead of Bitcoin, the price of Bitcoin would rise, meaning it would generate more profit, which would make people buy only Bitcoin. Therefore, it is not possible for people to buy another
proof of work coin instead of Bitcoin because this would make Bitcoin's price increase generating more profit, which would prevent competition.
In a normal company, competition forces companies to lower prices. In Bitcoin, the logic is inverse, it raises the price and prevents competition from emerging, which makes proof of work impossible to copy.
I’m confused. Bitcoin is not a company and does not have a group of people to decide whether they should lower or higher the price based on competition. Its price depends on the demand. If people’s attention shifts from bitcoin to other coins, then those coins’ price will hike up. Unless people who have invested in bitcoin start selling their coins, it’s not gonna do anything to the price. I don’t know how you think it’s going to work if people started buying other coins. People can allocate their money into different and multiple coins.
