Don't you think they just went too far with competitions like winning the Lambo? The tap earnings are very small and I'm sure most multi-account players have been caught out by the system. In my opinion, this site has become too luxurious and it's just a regular faucet and casino.
It's just how they attract players, especially big players who wager a lot... I don't see why we would call it luxurious, that's how business is done. And when the business is big and strong, really big prizes can be offered that will attract even more players.
Freebitcoin has always been a regular faucet and "not typical" casino with some betting markets and one game. Simple and effective we can say, but it attracts people to spend their money and time on their site. I guess so many competitions have something to do with that.
