I mean currently there is only aout 6k dollars coinmarketcap and with this price will be barely 10k when all coins will be mined. Much further free place for price improvement left, like VERY MUCH. We can't measure with such legend coins like LTC with 56Millions cmc, that would bring GP price to 0.44BTC per coin. But upto 100k shouldnt be hard at all. REMEMBER ONLY 6k coinmarketcap.
