Aye, until we get the outline of future lending plans, its hard to judge what a reasonable framework for interest payments on deposits is. I'd favor real flexibility in both : so the bank can both attract funds and lend them out with some regard to the risks undertaken ; i.e a long term player with good reputation and solid account should pay less ; a new player more, until they establish themselves. Likewise, interest paid should vary according to the banks needs for funds, and the need for long term funds with some mechanism to allow for withdrawals without upsetting cash flow to the loan side.
Otherwise, we may just end up with a secure deposit system, betetr than holes in the ground, but maybe not able to fund player expansion, etc..
