I'm curious how investing on gambling websites work?
Let's make an example that website has 100 BTC of it's own capital.
Then an investor come and deposit another 100 BTC. Total bankroll of gambling website is then 200 BTC
What does this mean? Does the owner and investor share profits 50/50, or has the owner more percentage, because he build the website?
Here is the best explanation and answer to your questions
http://bitcoin-dice-guide.com/house-investment-explained/Usually they'll explain how who gets what percentage of the profit share. It's never really 50/50 though. I'd be careful of investing in dice sites as well because most of them run off with users funds at some point.
No it is not 50/50 how could it be you have only invested some bitcoin the dev has built and maintained it and built the traffic to the point where you decide to invest, be happy with around 10%.
I have a hard time working out what you are warning here what dice sites are you warning about running with users money please name at least 5 for your statement to have any baring?
I will name 5 that have not Bitdice.me, Primedice, Justdice, pocketrocket,Rollin.io and many many more that have not ran anywhere and they could have quite easily an made a fortune so don't aim that at 'most' of them because it is an untrue statement is it not?
1. Ice Dice
2. Coinwin
3. DiceNinja
4. DiceBitco.in
Those are the ones that have run of with investors money that I can think of in the last 6 months. The intensives are perverse because the operator makes more money doing an exit scam than they make running the site successfully. What is needed is a trustless implementation with multisig and smart contract et cetera.
I invested ฿1 in the house bank of the top 9 dice investment sites and 3 have scammed me for the full amount, so 33%, not most but enough to make it a loosing proposition overall. All of those that have not scammed me are in profit, 3 of them a very healthy profit.

http://bitcoin-dice-guide.com/dice-investment-comparison/Wow great summary and info. I think it would be helpful if your comparison table also listed how long the dice site has run. Also do any of the sites have known operators with real identities?
