Yes, this one could be a decent alternative for crypto enthusiasts seeking for a betting exchange, but as I see exbet.io lacks efficient marketing and being active here on the forum. Last time they appeared on their official thread was September 14, more than 2 months ago already. Exbet is LIVE >> The Bitcoin Betting Exchange [exbet.io]

Many gamblers aren't familiar with this gambling category yet or don't see a benefit in leaving the bookmaker to bet person to person, and that may represent a big obstacle when trying to increase liquidity on such platforms. Anyway I appreciate their effort in trying to bring betting exchanges to crypto universe.
