Its currently sitting at about 53%. Its simply mind-blowing that even at record prices for BTC, all the altcoins are rising at break-neck speeds, which I assume is largely due to the dark hand of Wall Street. And as BTC is simply long overdue for a correction, I suspect BTC's dominance could fall within a matter of weeks, if not days..
"To HODL or not to HODL, that is the question." - Shakeyhandspeare
To hold or not to hold is not the real question, we know that if you hold bitcoin you benefit economically, what it is happening is that alts are recovering some of the ground they lost in the last months and to me that is natural, the price of alts was suppressed by the forks, since people were buying bitcoin in order to receive free coins and now that no important fork is coming things are getting balanced.
