This is legal or illegal? How much for the script?
This is simply a script which takes action based on the blockchain network, which is worldwide.
Different locations have different laws. It's up to participants to determine whether or not they should join in.
I'm still taking offers by PM.
Do you understand that your script can potentially help scammer steal money from innocent investors? If so they why are you continuing to sell it?
Not only can they but more often then not they actually do. I have not seen one ponzi site that has lasted more then two weeks without scamming.
That's like saying people who manufacture guns can potentially help criminals steal or kill. I'm not responsible for other people's actions. However, I am ignoring offers from obviously untrustworthy persons (new accts with negative rating etc.).
Edit: some people have been asking for a DEMO. I'll see if I can set something up.
