Books should post, definitively, what exchange source they are using when sending/receiving BTC
Bookmaker has never shorted me, but 5dimes has several times, the most egregious being one time shorting me $1500 , they blamed it on fluctuation, perhaps not knowing how easy it is to verify value at time of transaction being sent. Banged my head with the CS for days, finally asked SBR for help... and no joke, the SBR agent in charge of my dispute told me I was lucky I received my payout and should only pursue it if im willing to lose my 5dimes account.
