After some thought, I have only 2 concerns with investing:
1. My % of the bankroll will be so small compared to all the other money being invested that my profits will barely cover the transaction fee(s).
That's not a problem if the betting volume grows accordingly.
Exactly. Volume, especially on large wagers, is key. Plus, if the operator is sharing profits with investors, some investors will pull out if they see whatever they think is "too much" being diverted to operating costs/operator skimming, and that will lower the available winnings pool, preventing larger wagers. There's simply not enough data yet to determine long-term volume and the effect on dooglus' net rake.
I'd say give it another week or five, then SLOWLY and incrementally raise it
if needed so as not to spook the bankrollers. And be willing to lower it later, too
Remember - the risk is to the folks who have put in BTC (and I'm certain dooglus has put in a sizeable share, don't get me wrong...) and dooglus' risk is limited to his minimal recurring operating costs (at most a couple hundred bucks a month for hosting services, apparently at Amazon) plus his initial BTC, which he may have already taken back out for all I know. Well, that and the risk of getting the wallets hacked and having to repay, but I'm sure he's thought of that already
