Halving equals more scarce.
Halving equals less inflation.... it in no shape or form equals Bitcoin to be more scarce than it already. Scarcity in Bitcoin doesn't always play much of a role because during a bear market there are more sellers than buyers.
When there are more sellers than buyers, it can take a while for the ratio between supply and demand settles to a point where the price stops going down and moves sideways for a while to later start appreciating again.
Bitcoin holders must consider themselves among the luckiest people. There are many people who desire bitcoin and obviously it is not available for same rates as years ago. Even during dips, it remains an expensive asset. But the beauty lies in its form. Being digital, an investor does not need to buy a whole coin at one time. Also, coming years will just raise its value beyond our imaginations.
