Side note: sometimes millions bets may not be enough. Looking i.e. at the
BitVest's stats even after 4.7 billions bets, their profit is only at 47.6% of EV (assuming those stats are correct).
Hmmm... looks weird. Is there an official (or unofficial) explanation for this? After all, >4 billion bets should definitely smooth out all the statistical anomalies and give the expected figure. I think there are problems with statistics, often casinos hold promotions with bonuses and a reduced house edge (at least I read about such a promotion in a thread dedicated to investing in a casino bankroll) and apparently this gives such a distortion.
