YES! When you finish all 25 tasks in pussy market, the total coins amount you gain is about 26000. So the 30000 amount is VERY UNREASONABLE!!!
28k but you have to grind other 2k. +keep in mind that you have to have Mythic box in slot to complete last quest, which is painful enough to find...
I get used to save epic/legendary/mythic box when I fight in tower. So when the pussy market start I usually have some of them.
yeah, I use the same tactic, but thing is that Mythic box spawns is about once in 2 weeks (at least for me).
