So on bitvest with in 12 hours or so max betting and won over 60 btc.
He was down a bit of btc then turned it into +60 profit.
My question to you "Can a person beat the edge with a large enough bank roll?" Wow! This is amazing, I knew it that there are some people who are very lucky. And I admit it, that I am not able to beat this person.
But having a large bank roll will help you to keep on playing and give you a lot of chances and tries to win some good profit.
And the fact is I don't know even someone will have large bankroll still there is no assurance that we are able to beat him.
