There are many ways we can make money from this market.
I know many investors who become millionaires by buying good ICO/IEO/IDO.
I know many traders who have become millionaires.
I know many stakers who become millionaires.
I know LP farmers became millionaires.
And I know that many people with many other jobs like BountyManager, Advisors, Blockchain Engineer... also become millionaires.
So I believe that the best career is related to each person's abilities and passion. I'm a bounty hunter, but seems like a long time to be a millionaire ^^
