this is the rub. the higher in price it goes, the more incentive for massive fraud, & the greater chance that the G8 bans it as it does damage to more & more people. its just too easy to set up a merchant site then disappear with thousands of coin. This will not just go away like BTC longs expect. high prices will increase fraud, not cut it out.
so its fate ultimately resides in what the US & european regulators do. China & russia have already moved against it. Should there continue to be more goxes & silk road 2s disappearing with tens/hundreds of millions of dollars, the G8 is gonna drop the hammer & forbid banks from sending $$$ to exchanges.
& since the supply of coins are so limited, & cannot be managed, its impossible for it to be a currency because it will be too volatile. if you dont understand why, educate yourself on currency economics, & supply vs demand for money.
so its price will depend mostly on when the feds get tired of all the scams & forbid banks from dealing in it. its hard to predict when that will happen. But zero is the most likely outcome.
