Anything under 100 satoshi and I'll be relatively happy. If it starts going mental like 200-400-500 satoshi it will be overbought. The problem is now I want to buy more because I want my set amount of vidz coin and as I start buying more, others will fell the same and and then they will start buying more and then the fire just grows and before you know it the sale could be over with 300+ btc. I hope not tho.
