The real price of a tut is however much the purchaser is willing to gamble on an active tut. If that tut grows into an amount, then a new gamble occurs for the next amount they want them to be priced at. If someone looks at said tut and wants to gamble their money on it, then that person will hire that tut hoping for it to grow into that price.
The only time tutor pricing really is a cut and dry thing is with inactive tuts. They don't grow, don't drop stats. They remain constant, therefore a price can be placed on them.
This goes to helping tuts as well. If you invest a lot of time and money into a tut, that is part of the gamble you are taking in order to get a tb. You should price that tut at a gamble you hope one day they will grow into with your time and advice. Now if someone hires that tut, you can choose to hire back, which is once again gambling. In no way should this be deemed unlawful, or against the rules. Buying/selling tuts is part of the game.
I do apologize if you do not understand this concept, feel free to email ata at how confused you are at how the game works. No one owns tuts, it is about a gamble, a game.
