Lately players have been very lucky on dice as well. Dice profit of last 30 days is ~2 BTC for gamblers.
Not so good for investors, but at least it's a proof that house doesn't always win.
Speaking of investors (shameless self-plug):
My investment tracking thread is ongoing, and coming up on 1 year of tracking soon.
Currently there is data for the months December to August available,
with an update for the September returns (including the first time ever BTC investments did decrease over a 1 month period) coming in shortly.
A few key numbers as a sneak preview:
Over the last 9 months, investments increased on average by 11.735%. This equals to an average monthly increase of 1.241%, and it equals to an expected annual increase of 15.952%.
The highest gainer over this full period is ETH with a 23.786% increase, although the recently added BCH has already overtaken that by increasing by 24.851% in just 5 months.
Monthly bankroll rollovers have been averaging around 100% (between 75 & 136), meaning a full rollover, for the tracked period.
Notable exception is August, when the rollover was not 100%, but over 380%. Wagers have significantly increased in August, mainly due to big volume on BCH and ETH.
If you're interested in all tracked data and ongoing updates to the investment returns, take a look at the full thread:
