As far as I understand, this project has trustless storage of the users funds and the whole Betmatch as a betting house is immune social betting system with easy monetization. ALso it supports eth, which is currently more stable than btc, and i will choose ico and tge with such payments. ANd have you heard about zero-commission betting for token holders? What do you think? I'm now in doubts, this sounds perspective, but i want to be in black joining betmatch, so need some time to think of.
On their web site it is said "Users hold XBM tokens on balance. In case of placing a bet, tokens are frozen and commissions can become zero percent". Nevertheless, some formula exist, sounds easy at first sight, huh? In case you need, it is available in white paper. I've tried to download a screenshot of it, but failed as my bitcointalk doesn't work appropriately.
White paper you can find on Betmatch official website. Where everything is clearly explained.
