Here's what has been happening to bitcoin balances on the main exchanges:
Gemini's stash has reduced by 22,128.38 bitcoins in the last 30 days - and most of the withdrawals have happened in the last week.
Compared to a year ago, they have a third of the coins they used to. You can see a big drop in December last year - that was when Gemini Earn customers lost their coins and stopped using the exchange in disgust. (Gemini has gone silent about their Earn program - doesn't look like they'll compensate customers from their own pockets).
But it looks like withdrawals are picking up again. Perhaps this is a silent crypto-run. I honestly don't think Gemini will still be operating in a year's time.
