This might have been answered elsewhere but couldn't find it, if it has.
The miners get paid less and less as time goes on.
With the ledger also growing bigger and bigger, wouldn't the cost of mining start to exceed the profitability of mining? If no one would mine bitcoins anymore, wouldn't it shut the whole system down?
We can see that the price of Bitcoin continues to rise.
Hence, mining is still a profitable business. The cause of all economic crises under capitalism is the fall in energy consumption. Bitcoin solves this problem.
In my opinion, in the future, Bitcoin will become a guarantee of the stability of the global economy. The main holders of full nodes will not be individuals or even corporations, but individual countries.
At the same time, Bitcoin will be the official world reserve currency.
