You are offered opportunities, and make your own decisions.

As you are not forced to bid in any way, losing a lot of tokens but didn't get a player isn't anything but your bad decision.
Half of the game is about making good deals with a limited budget.

Offering 3~5 tokens (usually costing 12~20 tokens) to get a near 6* from negotiation may be a bit expansive for what you get, but it doesn't run the risk of losing biddings in 10 rounds over.

Of course you can get lucky and pickup nice deals with 1T, but to do that it's likely that you need to watch the market all day... which itself is a cost to be paid.
