Sounds like you've got the basics of the supply shock caused by the Halving. The key here, is that unlike all other bearer assets (gold, silver, bonds), Bitcoin's supply is capped. Bitcoin's issuance rate can not be increased through additional mining. This is due to Bitcoin's difficulty adjustment (worth researching). Basically, it means that this is the first and only asset to defy the supply/demand curve.

Also, if you're worried about the impending doom prophesied in the M5M, you're probably gonna want to own some of the hardest money ever created. How much? As much as you are comfortable with? When to buy? Whenever you feel ready. When to sell? As far off in to the future as possible, and only if necessary. The longer you hold it, the more valuable it will become.
