Maxed Bank Interest merit for me with no TCB shares is: 1.35% a week, 3.11% 2 weeks, 6,75% 1 month, 14,85% 2 months, 21,6% 3 months.
So your income would be roughly this depending on which period you invest in if you invest 2 billion dollars. (Numbers are based on the flat interest percentage no APR included)

21,60%
432.000.000,00
At these rates the most profitable investment is for 2 months, as you can have 6 investments per year which equals to roughly $1.782.000.000,00. While the second best investment is for 3 months, 4 investments per year which is roughly $1.728.000.000,00. If you work in an oil rig which grants 50% max investment in the TCB then your numbers would be higher, but best investment would still be for 2 months even with TCB benefit shares, as you would get over $60 million more, if you invested 2 months instead of 3 months for a year.
Well just some numbers and tables here, cause everyone loves those right?
