go back to fix a single mistake and come back?
if so then 10 million.
BUT, if I am going back at any place in time and reliving my life from at any point with my current knowledge?
i most certainly am going back.
i will be the richest person on earth - will buy bitcoin at its infancy and sell at its highest peak - buy stocks etc.
MONEY will NO LONGER be a factor in my everyday life decisions, nor natural disasters since i will know of at least the major ones that happened within my lifetime. I will be a deity and nobody will know how i did it
