I'd caution against speculation of a LARGE price bump from helium. They pushed the snapshot date out very last minute, and on aug 1st (original date) it hadn't accumulated more than 20% in the preceding days. That said with everyone's spec BTC freed up now after the fork i expect to see bigger swings across the board for a while.
I'll reply just once...(want to keep this thread mainly about mining SPR for now and not speculation. (Sorry I know I started it))
The snapshot push back was announced last week. Most likely due to the sudden new developement Bitcoin Cash.
Last week I think a lot of traders who were counting on SPR/HLM got the news the snapshot got delayed and move out to get free Bitcoin Cash. Before the news of Bitcoin SPR was outperforming market in general and in my guess it was because of the free Helium up for graps.
