It's interesting hearing about other countries because you're right, I generally only think about the 'big' capital providers but there are plenty of places to add additional liquidity to the market which will help prop up price.
Most of what you have mentioned in your comment (about new people being dragged in from price going up) is exactly what has caused Bitcoin to rise so much in the first place. So while it is a valid argument, there does have to come a point where it stops because it is circular logic (price is increasing because people see price increasing). It's called momentum, and I'm not saying that it will stop soon, but it is worth noting that that particular catalyst does eventually run out of steam. Thank you for taking the time to comment!
