It's already 'ber months, i really believe that this is the perfect time for bitcoin to pump up like old days, it is possible that bitcoin price will pump around $15000-$20000, so stay still and hold your BTC.
Actually, its hard to predict what would be the price of bitcoin on the last quarter of 2018 but I think the price will rise again or it will back to $20,000 or it will surpass it. As of now the price of bitcoin is still down and many people still hold their bitcoin simply because the price will pump up and it will go to the moon again.
