Nope, these tournaments are the very example of asking only for whales and not for regular players and unlike raffles and deposit bonuses, Tournaments offer absolutely nothing for the regular player and the masses and rewarding 1-2 whales with bankroll much higher than the average bitcoin gambler.

if it's a brand new site, then first give it sometime to gain a player base and show it's actually a working project not just a small site that will close in days, next is to start using faucet to see if you like the interface. Then deposit something small and try withdrawals.
Personally I don't see the need for a new website, if the older ones are working as they should...
