This is something that makes no sense... I can't understand how can someone that has a valueable idea think that he/she will hire a programmer to make it "come to life" and expect that the programmer won't "steal" or "copy" the idea for himself and just quit programming for others for peanuts altogether. Surely logic shows that anyone who does this, has no actual valueable idea and is just fooling himself... Which means that the programmer will receive his peanuts and the person will just get a useless "programmed strategy". I mean... WTF???? If the guy has the idea and knows how to code his own idea... I can understand that... But there is no way to code an idea for someone else e not understand it, even if the work is divided among different programmers, otherwise it would be impossible to code it... So that brings us again to the same idea: the only way to do this is to literally give the keys of the safe with the "Goose that Lays the Golden Eggs" in it.
