One of Altcoin will shoot high in price like BTC did suddenly and if so which one ?
yes, Unobtanium (UNO)
happening this very moment
the ride has just begun. Someone just called it 'the UNO rapture'
it is on a solid uptrend since july 2014 ... so quite a while already and i don't see a reason why it should stop. I think we could see price parity with bitcoin later this year.
