By 2028 halving, bitcoin will become more and more scarce because institutions and governments will buy it and Hodl while the weaker hands will sell all their BTC at discounted prices.
I am surprised to see halving count down for 2028 while we are still in 2025. Many things might change by that time, but I am sure there will still be bitcoin and it will be more and more scarce by then.
The good fact about Bitcoin is that it does not care if someone is sure or not, or what is happening around it. The decrease in supply issuance is preprogrammed, so the increase in scarcity is definite. Even if someone is not sure about it, it does not matter.
Hopefully with every BTC halving, the BTC price doubles. At least, that's the expectation.
Maybe, but not necessarily because it is already a very large asset class. Eventually the price must stop doubling or it will swallow all the wealth of the planet.

We may see a phase in the future where Bitcoin becomes a scarce resource.
It is already a scarce resource. In fact, it is the most scarce asset that exists.
