According to the fine print, you need to keep a balance of $10,000 to get that 2.25% rate. There have been points in my life when I've had that much money in the bank, but this is not one of them.
"Earn 2.25% APY when you have up to $10,000 in your account. Amounts over $10,000 will earn 0.50% APY." suggests that you get 2.25% on a balance _up to_ $10,000, not that that's the minimum for that rate.
