<prompt> Human: What are balance tiers, and what does this change mean?A tiered rate account is an account that may provide a different interest rate based on the balance of an account. Ally will offer three tiers: account balances less than 5,000 balances from 5,000 24,999 balances over 25,000Im not sure what to expect here. I fear it wont be good news for most people.Screenshot of email notice:  <response>: Also got this email, and had the feeling this meant I was getting screwed somehow. Would love some analysis. This plus the ATM fee thing from a few months back make me really worried about Ally.
