I think you have noticed that there are users on freebitcoin and other gambling sites who systematically reach the top of the daily/weekly leaderboards and win big prizes.
Yeah. Those are usually the whales who cleverly dominate the leaderboards regularly while the minnows wager and lose again and again. Basically, it takes a lot of money to make a lot of money in these contests.
Well there does 1250 doge.. the ammount of surveys I did, plus the stuff I put in.. what a waste of time. Fuuuuuuuuuuunnnnn.
Tough luck. It's easy to get phished if you aren't careful. This is why you always double check site names wherever money is involved.
