Anyone who asks me to use it with a larger amount is stupid.
1) ROI is ROI. Whether it's on 1 bit or 1 bitcoin the return percentage is the same.
2) Since the script fails 9/10 times, I don't want to lose my coin. I will never use the script on significant amounts of money, unless it's for investors
The script fails 9 out of 10 times? Not quite what you claimed in the OP, is it now?
Is it what she claimed in the thread where she was selling the script? This thread is supposed to somehow prove that that thread was legit. Therefore, to be fair, the standard here should be at a minimum what was claimed there.
Edit: A gambling script which fails 9/10 times is a hell of a
gambling script. Take a chance! 1/10 of the time, this script will win something! And yes, I would readily find plausible a claim that this script wins money at least 1/10 of the time on a site with a 1% house edge.
