Exacly what is the Reason bull run have not started yet?
There is allready good things happening Bakkt, Binance, bitmex large volumes and so...
Still that all its not enough?
Only mass adoption can bring BTC back into the bull run which is not happening because of slow transaction speed and no support from governement currently but I think soon governments would realize it's worth and with coming of lightning network it will definitely go to a bull run very soon.
