"10 years"?
OP was referring to crypto sportsbooks in general, not a specific bookie like Adkinsbet or any other.
Maybe You can consider Your decision to include Adkinsbet.com in Your topic?
Both Adkinsbet and 1xbit have ANN threads on this forum and are featured here whether we like it or not. OP made a topic listing bookies active on Bitcointalk. Even those with scam accusations to their names are part of such a list. Scams are unfortunately not moderated. OP has written warnings that both websites have scam accusations against their names and that should be enough.
