To maximize your profits you could run this bot 24/7 on a rdp. The bot will auto-calculate and take a percentage of your balance to use.
Don't expect to get rich from this if you don't want to put any investment in. If you start with the free 2 bits, you will see increases, but certainly not as much as someone who puts in a bitcoin.
This script has a negative expected value, as does any other script that disregards the bonus system. Running this script 24/7 will not "maximize your profits", instead it will ensure that you eventually lose your entire bank roll.
Programming and selling gambling bots is not reprehensible, but misrepresenting them as an "investment" is. And while you do not outright claim that your script is consistently profitable, you are certainly implying it. Potential buyers need to understand that this script is not a money machine.
