This has to be one of the most amazing crypto charts I have ever come across - it's the ETHE premium over ETH... it's transgressed across a 27% low to high of a staggering 2,015% ... insane. And it's in free fall - just dead cat bounced of a recent low of 34% and now sitting at ~50%... it almost makes more sense to trade this during market hours than regular ETH (buy when premium near lows and HODL till premium gets back above 100%? GBTC has a smaller premium spread but also function in a similar manner.
