Interaction points

If you've bought the max level albino radar, interaction points are pretty useless, my suggestion is that you can exchange interaction points for credits. like 1000 interaction points is 1 credit. Plus point: there is more use for interaction points negative point: the server could be laggy and it can be op for some users

No support, because you can already do that. Just buy another radar for 750k interaction points and sell it on the market or from ypur inventory. They are worth 125k which is a ratio of 6:1. Plus you need to charge your radar daily to keep the maximum boost. I use 100k interaction points and keep some extra. Then I sell or gift extra radars.

Albino radars sell for 125k. There are your credits.

This. If you're only putting in the minimum charge at Level 7, that's worse than "just above minimum" at Level 1.
