Yes they will eventually lose the capital. That is EXACTLY what will happen on all the various PMBs, "crowdfinance", "assets", "securities" and assorted scams out there that they patronise. The only notable difference is that just-dice takes 1% on the long term, whereas the troop of scammers take whatever they can get, probably about 30% or so net average overall.
Rather than trying to "invest" with some dead in the water t-shirt manufacturer or zero-hash waste heat producer or mentally-ill owned and operated Bitcoin merchant or "lend" with BitJam or "trade" with Bitfinex or what have you, the forum muppetry would obtain much better results simply rolling for it.
The only criteria they use are the rate of return, the only thing that interests them is for the intervals to be as short as possible (what monthly reports, weekly is too long for these people, they literally have the unchecked insanity to propose someone calculate the books daily and post their "winnings"). That's pretty much the extent of this magical "research" they do, that's their 'due dilligence". Why bother then with an ad hoc, informally-specified, bug-ridden, slow implementation of half of a dice site ? Why feed the scammers ? Just roll for it! Want 5% "interest" ? Want 3.5% "dividends" ? Load a Bitcoin or whatever you're "investing" into the dice site and roll for it. Your capital will on average survive for longer this way than your "invested" "portofolio" that you're "managing" would have. And you don't even have to wait, you can click the button for a new "dividend" period as soon as you're ready to see the results.
