Yes, I know all that.
The first was just an unlucky purchase before I even knew about FT thing. Bought the 18 y.o. thinking he will train well, but he didn't. Then I was experimenting and bought the second one to compare. Both were like 1 token + minimum price, so not a huge loss, but inability to sell them freely (without tokens, but at least for a market price of in-game money) is disappointing.
