I just logged in. It was a little slow but what GHS plunge? The prices have been around these levels or heading that direction for weeks.
Log in was also really slow for me, What caused the drop in prices?
btc has been pretty steady
The last two difficulty adjustments and the rise in BTC price has caused the drops. S3 has been pushed out the market and the S5 is next. S7 will only last so long barring a big swing upwards in BTC/USD price or some slower difficulty rises. Downside to the increase in BTC price is the increase in hashrate kept online or added!
Not to mention people worried about what will happen around the reward halving in July 2016.
Anyways all of this talk should be done in the Hashnest thread:
