$30M jackpot is sure to be the biggest. But it looks like you just want us to register under your ref link here.
Like they said I also can't find it being related to Coinbase nor Wirex. The only I can see is the egaming curacao license logo, not sure if its real. $30M is really big amount, I'd be cautious until I see someone win that $30M
Yes the amount is really tempting but we never know that this kind of site will pay the winner or not since there is no proof that they are holding this much coin. They just hope people try to buy it and gain some money to pay the winner. I do not really believe on some new lottery site. Unless they can give some solid proof. But it is based on Coinbase, I do not really fell into that
