Kraken limiting Monero. Prelude to total delisting IMO

Edit:

We can also guess they're playing fractional reserve games with Monero.

• Deposit limit: 10.8 xmr/mo
• Withdraw limit: 4.6 xmr/mo

The fact that they're letting you deposit double what you can withdraw means they don't have enough Monero on their books to make it up for everybody. Otherwise, the deposit and withdraw amounts would be equal.
