Then I invested the same $100 in 2009 in Bitcoins. What would my returns be in today's valuation?
What would have been the better investment? {Would surely be "Bitcoins"... but with how much compared with accrued interest, month on month}
Bitcoins were valued at 2 cents at some point of time when it just began, If you invested at that time you would have something like 5000
BTC which is about 2,500,000$ "not calculating it at BC peak value". I doubt it would be close to that between now and 2020 for example though it might be more than bank IMO.
