Altcoin is slowly becoming better than BTC the profit you make when you mine BTC is to low so miners are just stoping
and mining ETH,ETC,LTC,DOGE and so on but the thing is the less BTC is mine the more it will be worth think as it as Gold there isn't much and hard to find so it expensive and the price goes up and up because there is less every year same with bitcoin less every year hard to mine so next when the block reward is halved the price will go up maybe about 700$~
