What I know is that with Bitcoin, you own your own online bank at blockchain, If I accept payments with bitcoin or earned bitcoins from one of my invesment programs that means i will be able to send my bitcoins to a bank account to get FIAT currency without using an exchange?
yes, of course you will be able to get it. the bank will take care of it (an exchange). and most importantly that the bank already has a prior agreement or agreement on the matter.
