I think this is false information. I mainly invest. The bounty is only because I like its project to support it. Don't know how they got it?
if you are talking about a millionaire in terms of dollar, it's hard to know if other highly rank legendary members have accomplished that goal but in local currency like the Philippines where the ratio is $1 to 50 pesos it's possible especially if you are into bounty campaign 2 or years.
