I would think it's not sustainable in the long run, as it requires an inflow of USD 10 mln of new capital daily to keep it at the current level.
Why 10 mln daily? 2 mln EOS tokes come into existence every day and each one needs to sell at 5 USD to sustain the current price. Unrealistic but still not impossible.
That is why i hope it will decrease and i can fill my bag easily.
There is probably quite a lot of speculation going on, at least I hope so..
