Google trends image. What exactly is fueling this rally? This tells me it's old money doing the same all over.
It's similar to the $15 -> $30 run-up last time, just consistent and plentiful good news causing people with an existing interest in Bitcoin to buy in (possibly who learned about it in the last bubble but didn't buy). The media frenzy didn't start at full throttle until we busted through the all-time high.
