how to bet $10k without being in vegas

Good luck with that, online books limits are low, not to mention who would want them to have that much of your cash. If you are going to bet that much you should just fly out before the fight and add the cost of the stay in your bet (since you are sure enough to bet 10K on a fight)

Be careful  boxing is a shady sport, the fight game is the most fixed sport of them all and this high profile fight would be the perfect opportunity to make a killing off the betting public.

the feds get theirs no real way around this if you are a non national or part of us terrotorities then you can get this back.

but good luck only way to duck a ten99 is to make a series of wagers that once won will add to 799 in multiple places that don't have a common corporation affiliation.... 

only way to use these can be utilized is swiss or cayman islands bank accounts allow us citizens to gamble but the feds will not tolerate tax evasion.... swiss have a lose understanding with the irs but bank accounts must be obseen to become a issue cayman islands is a state unto itself. but incorpation proceedings need to be addressed buy a ticket go to vegas and gamble legal my best advice.
