He or she wagered 553.58634500 bitcoin during contest round 58 (April) and 12.09879000 bitcoin during contest round 59 (May). This accounts for a total of 565.685135 wagered, which corresponds to 113,117 golden tickets.
Where the other 153,145 golden tickets came from is a bit of a mystery, as they did not place in the top 10 during any of the other monthly contests. They either bought them, which makes no sense (why would you pay millions of dollars to win $200K?) or won them on the wheel of fortune, which seems highly unlikely (you would need millions of WOF spins to win that many tickets).
Thank you for those insights soslex I was wondering if you were still gambling at Freebitcoin. Do you have a personal hypothesis to explain the mystery of those "missing" 153 145 golden tickets ? Is it possible for him to have been outside the top10 in the other monthly contest rounds, like at the 11th or 12th position and to have been able to wager the required amount to get all of those tickets.
