At the moment the miners for a block are awarded 12.5 BTC. Every 4 years this value will fall by half. For example, let's imagine that the prize value is 1.5 BTC for each block and that BTC's value against the dollar does not increase. In such a case, mining will not be very profitable.
At the same time, miners are also benefiting from the value of the fee. This time the fee values will increase. Then people will have to pay a high fee for bitcoin transfer. The biggest advantage of the Bitcoin system against banking systems was that they could shop without paying commissions to any brokerage house. If this happens, can bitcoin preference be reduced?
No really, only the BTC reward will be lowered but the BTC price will increase due to the law of supply and demand, less BTC less supply more demand, high prices.
I am not saying that i do not agree with your idea, but your logic has a flaw. the amount of Bitcoin is constantly rising. Unless we destroy the same amount constantly, then the supply is growing. The rate at which the supply is growing is getting smaller, but the overall supply is still rising. So for the price to rise you have to generate a bigger demand. Constantly.
