250$ is not a joke and most the newbie here main goal is to earn on airdrop or bounty so there's no way they will risk huge money for a mere script.
Apart from the newbies and posters, there are many rich gamblers and other people who visit the forum. 250$ may be a big money for some people, but for the investors it is nothing. Some may even take a risk to see what this script is all about. So don't under estimate the purchasing power of the readers of bitcointalk.
Anyways, after seeing so many negative reviews, i hope no one buys this script.
It is not about purchasing power but it is more about logical thinking of members in bitcointalk. I'm sure there are many rich guys in this forum, but they wont be interested to buy something out of their logic. Even if there are no negative reviews, it is clear that there is no script called by always winning script. It is just a too good to be true offer to trust, people with good logic will not buy something like that.
