All the Altcoins I've invested money on are still in red, so I will be hesitant to assume or agree that we are or have actually arrived at an Altcoin bull run.
And besides, I don't think we can see significant Altcoin bull run until bitcoin pumps to lets say $100,000 and above, but worst come to worst, $75,000 to $80,000 should be a trigger for most Altcoins with good foundation and fundamentals to become to move up..
So, in essence, I do not believe we are likely going to see Altcoin bull run without bitcoin first opening the door, so, until bitcoin races up to $80,000 and above, I can not believe or assume that the current Altcoin gains is a sign of Altcoin bull run.
