I have personally experienced all the 3 investment opportunity and i must be frank with you that there is no other investment opportunity that brings a better return on investment like cryptocurrency. The truth be told.
Please, dont get me wrong, i am not in anyway saying fixed deposit or treasury bills are not good investments. I even maintain a fixed deposit myself.
What i am saying is that instead putting all your funds in just one of them you can split it into the 3 investment opportunity.
All of them as its advantages and disadvantages though. Overall, they are all good.
