Buy decorations if you don’t have enough offers. It can act as a “bank”. Withdraw when you need it,
They act as “EXP” as well because since I am max level, I just stash them in my market without collecting the EXP. If we were to have a new level cap, I should be able to reach max level fairly quickly as well.
I read that you stopped subscribing for VIP gabochido, I still have mine - the extra trades helps get rid of some coins. So, my first custom trade might cost me 25M-75M and then I save up a couple hours to max coins again and go for a second custom trade, repeat again for 3rd trade.
I usually get a couple offers of either Food/LP/DNA/DB throughout the day and I take them all and worry about max coins later.
Edit: It just crossed my mind that a handful of players are trying to clear market, so this would be different for them. I play very similar to Tommi though, I keep and hatch everything. Having a full market doesn’t seem to affect my game. I get good offers of LP/DB/DNA all day. Mods doesn’t even appear too frequently for me either and I kept all the mods since I started playing, still have all my legendaries.
I have even sold Clock Towers for 600+ DBs because they only costed me coins.
