The price of Bitcoin is going to down and I think it will be continuing some more days. But after some days, price will be starting to rise again. It is not on stable stage.
Bitcoins price had never been a stable thing since from the beginning.It is always volatile, it might have some days where it do move sideways
and with those minimal kind of movements and this wont really be called a market if price would become stable or wont move.
In the question if its sustainable? Then, this do talks about demand and that what makes price do moves.
