I think interest is great. However, since that it takes a year to maximize my yield, I would like to have a command that shows the distribution of coinage in specified account. For example:
>>coinage <account>
And it may returns something like:
1. Coinage of 50% of balance is 0.9 year
2. Coinage of 30% of balance is 0.5 year
3. Coinage of 20% of balance is 0.1 year
So I know I can use the 20% without interfering the interest of the other 80% to maximize, assuming the wallet will automatically choose the 'youngest' BitUSD to spend.
