Gemini wallet balances do not include Gemini Earn balances. When you transfer from Gemini wallet into Gemini Earn, CoinTracker shows balances reduced by that amount. It made me think that amount had been transferred out of my account at first.
Gemini just launched a staking program. I noticed that Cointracker recognized that I sent some currency to Earn, but it's no longer tracking it there. It would be great if that can continue to be tracked in Portfolio here.
