How can that be? With a 25% commission for the house, this will remove 25% from the profit of the investors and it will add 25% to there losses. Now, while an investor has a profit, how can a 25% commission remove all the profits + more, so that his total investment goes below his original investment?
Either I am missing something huge in how investment works, either there really is a problem somewhere.
The commission charged isn't on profits, but rather on the amount wagered. i.e. Even if a gambler breaks even, investors will be a loss. Investors will only make a net profit when gamblers lose > 0.25% of what they wager (which over the long run they should, as the house edge is 4x that)
