I'm highly doubting you actually wrote this script. Your story doesn't add up if you were custom making it for a client...

I think that you likely found some crypto sports book on github somewhere and are trying to make a fast buck but tricking some idiot..
If you want to sell this script you've "wrote" then I highly suggest you attempt setting up a server and showing people this shit actually works.
This will let us determine what script you've ripped off as well.
