Yes, the price is underestimated, relative to other sites when selling, but!
Instant redemption, the money on the card arrives in 5 minutes maximum, on the balance with an additional payment you can buy something more serious and (importantly) also at a strong but zanzhena price. If you compare with the x go market, that there is worth 10 - here 9 . The redemption price is commensurate with the price difference between the sites. I'm not saying it's perfect, but it's fast and clear. When I needed a bike small, I sold the knife and went to the store immediately, rather than sitting for a month hoping for a sale (and the price of autobuy at others is the same as here +/-).
