Also Dooglus, I would suggest making investors pay for each divest they do. However give every user 1 free divest per day.
This will stop the daytraders that are creating more negative EV for the long investors, and also its still fair to those people that needs quick access to their coins. A non day trading investor will not have used up their free fee and thus have nothing to worry about.
I don't agree that daytraders are creating negative EV for long term investors. By being divested part of the time they increase the long term investor's share of the profits, increasing their EV.
It's common for players on the site to invest between playing sessions. I don't think it's fair to penalise them doing so by charging them an extra fee each time they divest to play. It makes them less likely to play at all.
Daytrading is not creating -EV for long term investors, but a cold hard fact remains: those who invested at site's inception and never divested are now stuck with a huge +30% loss, despite of the +3M btc and 150M bets wagered. Crazy stuff, as the numbers seem large enough for the house edge to be working fine.
Anyhow, your point about a divestment fee discouraging divesting to gamble is very spot on, I guess we are all just brainstorming to find a solution that makes the site more profitable for investors that fund the bankroll without divesting and causing "bank runs" that make you and other investors nervous.
Mechs: I criticized you hard for putting pressure on doog to cripple max profit, and I still think that was a big mistake. We went to 1/4 Kelly in the middle of a session in which Nakowa lost 5k. You and some others believe this loss was caused precisely by lowering max profit - I believe that's baseless, lucky numbers didn't change and IMO a higher max profit would have led Nakowa to lose way more, but we will never be able to find out who is right.
Nevertheless, I perfectly understand the reasons that made you nervous, and I felt extremely bad for you when I read about your loss. I'm very happy you sorted it out, that would have been a mind blowing loss.
Just let me recommend you against "picking pennies on a train track" by betting thousands of coins at 92% odds, you will want to kill yourself if you'd lose such an amount in such a stupid way now that your anger is taking over.
