I'd love for you to criticize it so I can make it even better.
As per the script in it's current form, this will work approximately 9992 out of 10,000 times (the chance of you losing your entire deposit is 0.074990933%, under a tenth of a percent).
Here's my criticism: You are claiming a 99.92% success rate for a 15% ROI, which is even more outlandish and ridiculous than your previously claimed (and thoroughly debunked) 90% at 20% ROI. This new script is even more obviously flawed than your previous one.
I'm not saying this in a condescending/snide/patronizing/arrogant way. Please seek professional help.
