Please give some fundamental or technical reason. I don't believe so it will go even low from 7500$. Bro the thing has a value and worth 9000$ in real world, by assuming antiminer fee, pool fee, electricity cost and time required plus the maintenance fee of antiminer or rig. So even 8500$ value of BTC is less than its true price. It is quite a good time to buy or you will regret later waiting for 6000$ price.
