I would guess that worst case scenario would be going under 40k, and that is not really that bad. People talk about worst case like bitcoin going down is bad, but the reality is that if you do have money on the side, then bitcoin going down is not that bad for you, it would be able to recover and do a lot better.
Because you could buy with the money you have, when it's down, and you will wait and get a lot better with time as well. It is not really that unheard of, every bear market people with money end up buying bitcoin, at lower end, and then they wait a few years and sell at the peak. This is a very legit way of making money and I feel like we are going to see this grow a lot bigger on the long run, shouldn't really be worried.
The investors who make the most money in the market are those with large capital, who hold for the long term, and who know how to take advantage of opportunities to buy at low prices.
Therefore, I do not think there is such a thing as a bad scenario for Bitcoin. Bad things only happen when we are unprepared, when we do not have a backup plan for market scenarios that go against our prediction.
If Bitcoin falls below $40k, that would be the best case scenario for us.
