I heard that many of the crypto casinos were really considering it for a while, but in the end they were just chickens hahahaha 
Can you point out on which those "Chicken" casinos do say that they might be considering on adding it up? 
So far, after all the years that i've been lurking around on this market or forum, then i dont really see any crypto based casinos which are really having plans on adding it up.
Its not really that shocking though yet its not really known worldwide on which means that demand is less, therefore it wont really be shocking that these businesses or platforms wont really be
having those kind of considerations for some possible add up.
Somehow, into those people who do really like on betting on cockfight then they could really be always to do such thing on which we know that there's really a specific
platform or site on which you could really make out those bets but of course it is really just that solely created for cockfighting and there's no other
games which are available. You could always have those choices on what to deal with.
