Normally I don't make predictions, but I believe Bitcoin is headed for a blast from the past. Perhaps around $700 mark. Then when all the FUD from the upcoming segwit on Aug 1 clears, all the people that sold will be kicking themselves just like before.

There was another article in the Wall Street Journal this weekend about the risk in crypto currencies. Not sure it'll tank as low as you predict. But I could easily see 1100-1200 for BC unless the segwit ends up being a major clusterfluck. I can see ether tanking to below $50.

John McAfee Vows to “Eat His Dick on National Television”; An Extremely Bullish Ride

Cybersecurity guru and libertarian presidential candidate John McAfee’s thinking follows alongside Moas, except McAfee tweeted to one of his followers today that if his predictions fail to materialize, he will dine on his own penis in front of everyone. McAfee made the comment after saying bitcoin will move above $500,000 within three years.

That almost makes me want the price to NOT reach $500,000 within three years!
 
I've got a rig now up and running with (4) GTX 1080 Ti cards. The honeymoon with Nicehash is over as they're paying about 1/2 what they were two weeks ago. Ethereum has a spiking difficulty level. So I'm looking to put on my big boy pants and mine directly. Any suggestions?

My understanding is the difficulty bomb went off to get people to move to Proof of Stake, but now they're not doing it as scheduled and they should have reduced the difficulty back down.

Was thinking that mining with Nicehash is kind of like mining for milli Bitcoin, while the exchange today may not be optimum, if Bitcoin really goes to the moon the maybe Nicehash is the way to go.

I suppose it is, in an indirect sort of way. The buyers are paying BTC for you to mine various cryptocurrencies so ultimately the price of BTC will effect miner earnings to a similar degree that directly mining BTC would.

I'm probably gonna stick with NiceHash for now. My NiceHash earnings in £s are about 25% less than they were a month or so ago, but in terms of BTC earnings the difference is much less. The way I see it, if the price does go to the moon in the next few years, what I'm mining now could be the equivalent of tens (or even hundreds) of thousands of pounds per month (assuming I hold it, rather than spend/exchange it).

Hi guys,

I tried out the TREZOR, finally. It's pretty nifty. Very easy to use--you go to their website to sync the device. You're often asked to look down to the device to complete things on the page (such as entering a PIN, and the numbers jump around on the device/you can't see them on the computer for added security). Nice clean interface. No issues during setup.

Really glad I bought the thing since I'm starting to put more into this. Any questions, let me know.

Thanks for the update. I really need to get me one ...

So you use it with their wallet software, right? (rather than Electrum, etc). And I believe it supports lots of different cryptocurrencies -- is that correct?

I noticed this encouraging article about the Trezor while browsing the cryptocurrency news this morning:

Weird, anyone got any ideas on this...

Two PCs.

ROCKETSHIP: two GPUs, a GTX 1080 Ti and a GTX 1060 6GB. The CPU is an Intel Core i7-2600K @ 3.4GHz, 8GB RAM
MINER: has four GPUs, all GTX 1080 Ti cards. The CPU is an Intel Core i3 550 @ 3.20GHz, 16GB RAM

The 1080 Ti cards are all the same make and model. For the rest of the discussion, ignore the GTX 1060 6GB, the numbers and stats I'm quoting do not include that GPU.

The single GPU in ROCKETSHIP is hashing on Lbry around 481 MH/s, generating 1.23647 mBTC or $3.23 / day
The GPUs in MINER are hashing around 450 MH/s for GPUs 1-3. GPU 0 is hashing around 350 MH/s, generating 4.42223 mBTC or $10.11 / day.

The cards in MINER are set for 75% power, + 100 GPU clock and + 500 Memory. The card in ROCKETSHIP is at defaults.

GPU0 in MINER is connected to a display. The 1080 Ti in ROCKETHIP is driving a display.

I've noticed similar results since I've had all these running. I would expect that 4 GPUs would earn 4x 1 GPU, but on casual observation it hasn't appeared to be so, including today.

Possible explanations:
  1. The more powerful CPU in ROCKETSHIP is helping with this algorithm, Lbry
  2. Some of the tweaks to the cards in MINER are hurting it in some way
  3. Nicehash isn't linear, if one card makes $1 then 4 cards don't make $4
  4. Nicehash is inconsistent in some other way
 
One other thought: on ROCKETSHIP the GPU is plugged into the 16x PCIe slot directly, like a normal graphics card. On the MINER PC they're all plugged in using PCIe 1x riser adapters. Maybe more bandwidth to the bus is helping?
 
More testing. Only mine on 1 card on each and compare. It seems that GPU #1 on the MINER is not working hard for some reason. I set all the values back to default. Clock speed of it's GPU is 1544MHz. On ROCKETSHIP it's 1900MHz. 360 MH/s on MINER, 478 MH/s on ROCKETSHIP.

However, head to head competition between GPU #2 - #4 against the loan CPU on ROCKETSHIP, they're identical. Same GPU clock, same hash rate, etc., tested one at a time.

So I powered down MINER, waited a little while and fired it back up. GPU #1 runs better. Clock rate goes to 1936 MHz, but hash rate is still a little bit lower than others: 433 MH/s vs about 478 HM/s on all the others.

I connected the display to the second GPU and it's performance dropped accordingly and the first GPU improved to match all the other good ones. I even tried connecting the display to the on-board video port of the PC, but I got no display on POST and the second GPU still performed worse. Guess it still thinks the display is connected.

Conclusion: whatever card has the display attached to it will perform worse.

Possible reasons: PCIe 1x riser? Slower CPU?
 
Yes, adapters that have a display connected will fare worse.

I'm on the hunt for low cost farming equipment and noticed this:

http://www.ebay.ca/itm/MINIX-D2500-...id=100005&rk=3&rkt=6&mehot=pp&sd=263073865172

12V Adapter? Check. PCI-E Slot? Check. AMD64 Ready? Check.

The only things is I would need that adapter AddPSU, which will use the Molex output to sync another PSU. The wattage on the Minix boards is going to be around 10-15 W, so they easily win for keeping it low power. Plus I can fit more of them in my rack than a full featured board. Plus, it uses DDR3 SO-DIMM which I have tonnes of.

Currently because I have older boards I can only run two cards at a time, so I tacked two boards. So each board runs at least 100W in idle. If I were to get the Minix boards, I can reduce that to 60. That's a savings of 140W.

My Nitro cards eat up 220W each and the RX 480's use 150-200. So this could be a way to go. Ditch full scale boards and go modular. If one system fails, I only lose one card. Plus these are cheap enough I can order spares.

In my rack I could fit 6 of these boards maybe even more plus the risers. The only trick will be to sync the PSU properly. But not too much of an issue. Because the boards use DC 12V, the risers only have data pins for any connectivity to reference ground, so sharing a PSU for multiple cards on risers isn't as risky because all the risers and cards would get power from one PSU, even if one system failed, the load would still be enough to keep the PSU stable. Hmmmm....

I can call it a micro rig.
 
Damn, it's still not 100%. Here's the MINER after running a few hours, currently Libry. Notice the hash rate is now below 400 for the GPU #0, the one with a display, around 390 MH/s... AND, the other three cards are well below how they tested around 440 MH/s instead of 480 MH/s.

Here's the single card in ROCKETSHIP:

Still humming along around 480 MH/s.
