Holy hashrate, Bitmain!
My theory with drop in difficulty lately it's my initial A3 buyers decided to sell the units on ebay etc and the units were not running while being shipped. Now they are all coming back online and difficultly will return.
The drop in difficulty was due to block times. This spike, whatever it is, is equivalent to 3600ish A3's being turned on.
Yes. Confirm the calculation of ~ 3400-3600 A3s coming online within very short timeframe, ie. 2hrs. If this is the source, then only one capable of that is BM.
There's been a decent amount of speculation as to why Bitmain is selling batch 2 at such low prices. Look at what Halong Mining claims*** to do (they still have not shipped a single unit of their SHA256 miner to date so this is very TBD) with a miner that can hash SHA256 at 16TH/s, slightly higher than the S9. If they are now claiming that they have a Sia miner at 3.5TH, I would not be surprised if Bitmain has an "A3+", "A5", whatever you want to call it around the corner. I don't think Bitmain is dumping stock because of the SC1, I don't think they're dumping because of the B52... I think they've been able to massively iterate over their first Blake2b miner and are going to crank the game up a few notches here soon.
Well, I can only claim, that Bitmain is 'likely up to something' they constantly surprise me with their attics...since they yanked my miners off the eastshore.xyz truck last summer to
mine them for 6 weeks to stop seg witness on LTC! On a firmware problem.....they showed up with Jan 2017 firmware...rather than supposed Jun 2018 fix.. lol ...did not even try to justify
their lie, with the simple step of changing the date!
So yeah, I am sure Bitmain is up to something *you don't make 2.3 billion last year on miners w/o 'real' evil skills)
bitmain: we got the evil skills ...if you got the evil greed....lets do this! (bitmain: its always a trap!) (tm bitmain)
