Well, If you spend the free 20MBL given from Matchbillion.com site then you have to purchase it.
0.01 ETH = 140 MBL
0.001 BTC = 420 MBL
There's no way to get more tickets asides from buying it. Or having affiliate incentives might help you that.
After buying MBL tokens by ETH or BTC, if I want to get my ETH or BTC back, can I sell MBL tokens to get ETH or BTC on Match Billion site? I read that Match Billion team have plan to bring MBL token to exchange, so I would prefer to know progress of the exchange listing for MBL token. Are there progresses months after the born of Match Billion site? It is safer for gamblers if they can sell MBL tokens on exchanges, rather than only on the Match Bilion site.
I did not the site for a while but I think there is still no ways for users to exchange their MBL to ETH or BTC on the site. Means that once you bought MBL then you'll keep it as MBL unless you won the BTC or ETH prize, but if you won MBL only so the only thing you can do is holding it or keep playing. This is the disadvantage of this site that makes people think twice before they buy MBL. IMO, the best thing to do by owner is by adding an option to play the game without buying MBL first, so users can play with BTC/ETH directly.
