Not sure how innovative it is if it is already happening on Chinese sites/ Casino's , I am sure poker sites would have had this idea but it kind of takes the gamble out of gambling. I have never seen it on over 10 class fiat poker sites that have many quality thinkers/staff and 5 btc poker sites that are totally average. Not one has this insurance but who am I to say it can't work I will just say I would not choose to play it and if forced by the site I would not play on the site. Note: I never use insurance on blackjack for this reason.
Same as me, I never use insurance on BJ either and I agree insurance sucks the life out of gambling, if a player don't have the guts to go all in without insurance then he should just quit gambling once and for all.
And I think it can be abused also using shills, doesn't really helps the site in anyway either.
