In my perception, the next bull run will be initiated by a mass migration. I can observe people getting fruestrated with FUD about bitcoin that now they are looking for a more useful coin to transact with. The second in line ready to take on BTC is the forked version -- BCH. BCH had been on a good pricing lately and this is slowly catching the attention of crytomigrants. If this will continue to make a roar, then we might be seeing a slow death for BTC.
