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..

Altcoins are getting pumped as a whole today, i thought i actually saw bitcoin dominance decrease to nearly under 50% today and now it's recovered back up to nearly 51%. So we're basically hanging around that half BTC/half altcoin region.
Eventually i think we will see bitcoin dominance crash just like back in March. Altcoins are increasing in price fast and bitcoin will too, probably to $25k soon but i just don't think it's going to match alt's growth.
In the end though, this is a good time to buy bitcoin and dump alts since the ratio is so low. It will recover eventually to 90%.
