Big hashrate jump in the last couple of days. Is HashFast testing stealing customer profits prior to shipping?
I actually haven't seen a hash rate jump as much as I've seen good luck. It's mostly good luck and minor hashing additions check the hash rates of top 5 pools.
Luck doesn't explain the grey line here:
http://bitcoinwisdom.com/bitcoin/difficultyThat's a 504 block average and a decent jump. A good amount of hashpower looks to be coming on and off line since the beginning of the month. A 1 PH jump on a 504 block average is doubtfully due to luck.
I could be wrong, but to me it looks like a large batch of ASICs being tested or a large number hitting customer's hands. I don't think the latter has happened recently.
