Supply and demand is what determinate the bitcoin price as well as the bitcoins being traded, if somehow a bunch of bitcoins that weren't been used enter
the market expect the price to come down very quickly.
It's not just supply and demand. Markets aren't fair place unfortunately
I think in world exchange? U.S of America dollar is too high today. So I think that is the one possible answer to that question and my other thought is there's a lot investors in bitcoin so that the price is continuously raising and that is a good sign that we should invest at least 10% our salary. and that's not bad.
