As per my experience , this is not fake bull run. this will be bull run , but do not expect 50000$ per BTC. BTC double ,means from 4000$ to 8000$ went in a short time , last 2 month it drastically moved up.
I am sorry but what is your experience?
Did you experience more bull runs than others? That is the only one which have appeared in this world the runup to 20k BTC ?
I dont see no real arguments because we will experience altcoin bull run just pure speculation.
