US and global markets are looking shaky. Probably things will recover in the short-term, but a long-lasting global recession doesn't seem far off. There are good reasons to think that it might be even worse than the "great recession", though you never know. How will this affect the BTC price?
On one hand, a lot of people might want to sell their BTC and move back to traditional investments while they're low, especially if they got into BTC in the first place as a way of getting better return-on-investment vs already-peaked traditional investments. On the other hand, people might lose faith in the fiat economy entirely, especially those who have already taken the step of buying BTC.
