If they claim it to be in Beta Stage, then for the time being they should only have allowed depositing and placing bets through a test coin.
As they have done this, this proves they don't have any professional behaviour mannerism.
They just launch the site in a hurry.
No proper investment no proper management and these are the things which many people frown upon.
As you can see on page one, they offer 11 satoshi for new players which verified email to the testing website. but the problem is the new player can't play that 11 satoshi (
oh noez, error: Invalid Parameters), so what for a bonus when trying website must deposit money?. Also, OP never online since a week ago, it's very risky of playing without any confirmation.
the error occurs when they bet 11 sats or lower than that ? people should report this so that they can fix it or if not then they should increase the bonus amount .
you already read the page 1 but you didnt read the next page? for feedbacks if the site is safe to play or not . the issue is for the bonus coin , i dont find that risky because we can always depo our own money to play .
