This growth looks suspicious to me. Was there a major announcement or something? I know it's not the first time BST passed $1 but the jump in price happened in a moment and that is not natural.

This could be a bull trap you are right this looking suspicious. There is no announcement or release in pipeline but the big question is that how long they could maintain the current level. It will be very hard task to keep sustain on the current level of price.
We will be issuing medium article to address the price changes, anyway seems new price level is stable
