Eduardo Saverin

http://en.wikipedia.org/wiki/Eduardo_Saverin

Facebook cofounder and billionaire. Fun facts:

– Saverin took advantage of Brazil’s lax insider trading regulations and made $300,000 via strategic investments in the oil industry.

– he renounced his U.S. citizenship; the citizenship change may have reduced the capital gains taxes Saverin would have paid after the Facebook IPO.[7][20] In response, Senator Chuck Schumer introduced the Ex-PATRIOT Act, which could have prevented Saverin from ever entering the U.S. again, but the bill died in committee.
