RPX is holding much better in terms of Satoshi...Since 16600$ its stable around 320-350 Satoshi.
Well The real reason is many weak hand had been shredded off
and people witnessed it being pumped around 600 Satoshi.
One thing is sure from the pump is that something huge is upcoming
I am sure by Q1 2018 we would see RPX around .3$
Best of Luck

BTW the team is awesome and doing a wonderful real world job...
