I've maintained throughout that the script has a 90% chance of winning and 10% chance of failure... I don't want to risk 1 BTC on a 10% chance of failure, simple as that. The ROI is currently being proved daily anyway
Back atcha: If the script wins 90% of the time and has positive ROI over time, then you shouldnt worry about risking 1 BTC. ROI, yes? Youll make it back, then make more.
Just like your investors.
