Well, everyone's investment so far hasn't triggered sustained buying. There is no reason one more will change anything. Incentives are stacked against participating before the absolute last moment. I suggested OP to change slightly the structure of the ICO to neutralize the self-reenforcing effect of the wait-and-see strategy. It's up to OP to decide if he wants to help his own ICO. It's not my role trying to bootstrap things on his behalf.
