Last week, probably the most spectacular freebitcoin lottery win (of all time?). A user managed to crack the jackpot with a puny bet of just 2 lottery tickets (worth under 1 cent!).
The popular Bitcoin Faucet freebitcoin.io not only gives away bitcoins every hour, but also offers other ways to get or win Bitcoins for free. Among other things, a lottery is operated, this is completely transparent. You can even see the servers, so that manipulation is excluded. One can buy lottery tickets with the paid in or won Bitcoins, but one receives also for each time Bitcoins pick up lottery tickets for free. Every hour, 2 tickets will be added. All in all, each lottery lasts one week until it is randomly drawn. The more tickets you own, the greater the chance you will be among the top 10 winners.
