It is unbeliaveable to hear that you became a millionaire in 2015 as  you learned about bitcoin in 2015. That time there was no future trading options too. So how can we believe that you became a millionaire on the same year you heard about it when there was not held a big pump in 2015. If you bought btc in the lowest price and sold it in the highest price then you just made a little price which is not a million.
