The only difference is the name other than that it is guided by the interest musical chairs votes.
Let say I am in team Corona have $11,000 according to my post counts, but the maximum to deposit is $2000 (mix and match on any bank I want except I cannot deposit in my team's bank (SunBank) ) I can deposit $1000 in RegBank Saving and $500 in GeoBank Saving and $500 in GeoBank Money Market Account.
Then according to this:
RegBank Saving Account: (44) (-2)
RegBank Money Market: (50)
GeoBank Saving Account: (69) (+3)
GeoBank Money Market: (49)
SunBank Saving Account: (54)
SunBank Money Market: (50)
I have $1000 + 4.4%($1000) and $500 + 6.9%($500) and $500 + 4.9%($500) =
$1000 + $44 + $500 + $34.50 + $500 + $24.50 = $2103 by the end of this interval.
So keep voting for your opponent teams' banks because that are where you allowed to deposit money in.
Lets hope that shed more light to this confusion.
no one understands your directions 
but at least you could warn me, I don't understand the challenge
