Can you send me to the FAQ page that explains the bankroll Investor details further?
I can't directly link to the details, but about 3/4 the way down the help tab there is the explanation of our investor system. I've quoted it below, but there are some extra details upon hovering the terms in the help section.
You may invest in the site's bankroll to earn a cut of the profits. You may also invest on margin to have a proportionally higher risk and reward on your investment.
Except for token bets, all winnings and losses are funded by, or paid to investors proportional to the size of their investment.
To support Bitvest, a fee is taken from all bets leaving the remainder of, on average, 1.15% of all Plinko, 0.75% Dice, 1.155% Slots, 1.155% Bit Spin, and 1.833% of Roulette bets paid to investors.
You may invest or divest your funds instantly at any time, and you may invest with a margin of up to 500% or 10% (2% base * 5) max risk.
If you require more details, I can answer and questions you have.
