The mining thing is already obvious.
Illegal markets won't do anything for the price.
Only mass adoption will, and by now, almost everyone has heard of bitcoin. There is no spike up ahead.
Mining has still not been accounted, there will be more fall to come, until it reaches the agreeable production cost level, and only from that point onwards there will be a spike and price determination. I may sound bearish, but it does not harm to see the real picture, the price shot up without any support, happened partly china, partly due to horde for ASIC boom. Many ASIC farms will not be sustainable.
As for illegal markets, like or not they still are driving the price, take them all away and see the impact on the price.
