We profit 76 % of the time over 1,000 bets - not 50.8 % of the time like with 1 bet.
THAT'S being an investor, not a gambler.
Also - has anyone noticed that despite the 1 percent edge JD has never made a 1 % profit? It was about half that - before the current fiasco - now we know why.
Variance. Lets lower it by refusing big bets.
I'm sorry, but this is the biggest load of BS I have ever read. Clearly you have not done the math.
If you make 1000 bets with a 1% house edge, you will win 490 times and the house will win 510 times. The house will not win 76% of the time.
Variance means nothing as far as house edge. Playing many tiny bets and playing one huge bet provides precisely the same house income over time. As a gambler, you will have no advantage by placing smaller bets and winning and losing small amounts than by placing a single large bet. Over time it's just a matter of scale.
A casino runs the risk of losing the bankroll only if they don't cap the size of their maximum bets. Because obviously there's only a 51% chance of winning that bet, and thus a 49% chance of going bust from the casino's point of view. But JD does have these limits. Noone is placing bets of 1000 BTC or more. The max win is 1% of the invested capital, which makes good sense. There is no reason to limit that further.
What we have here is a situation where someone appears to be actually beating the house edge over many thousands of bets. And this is intriguing, because from a statistical point of view this should not be possible. You can't win a coin toss came if the coin is balanced towards the house, no matter what system you use.
