So 1 compac usb stick  from sidehack





If you are overseas  I will spring for the shipping of the compac stick. Note the compact stick is the 1 chip version but as always it is fun to play with it.

10) Finally If I missed anything  I will be the sole  decider as to what is fair.

Let's see how this holds up over time.
If it works well enough, feel free to quote it Phil.

I have my SHA256 miners on NiceHash with a profitability value. That last difficulty increase was so high that my miners switched away to a backup pool.

It's days like this that I wish NiceHash had listed to my request to optionally specify the profitability as a delta percentage rather than a fixed value.

Let's all hope the next jump goes easier on us...

[QuintLeo]

How do you get your ASIC miners to switch pools based on profitability?

 Is that SHA256 specific, or does it apply to all of their ASIC-based pools (I seem to have missed it in the Scrypt instructions).

On the s-9. The third line the password line

.42

Would be the setting

As .33 is the correct rate

If no one is paying .42 it drops to second choice

If you get paid the .42 it is like 135 percent.

For what it's worth, BTC price has declined now to $2051. I would think that if that persists, that the increase in hashrate will slow. There's quite a lag in hashrate changes, BTC price can literally "turn on a dime". Maybe a decline in BTC price coupled with good sized difficulty jump will bring things  back closer to where they were back in the first 2 months of the year.

Just my $.02.

I cashed 4 coins at  about 9550.
I could buy them back at  8300.

this chart shows a drop  the gray line is clearly under the line.  which means negative.

I would not mind  a further price drop.
say  1600 a coin.

How do you get your ASIC miners to switch pools based on profitability?

 Is that SHA256 specific, or does it apply to all of their ASIC-based pools (I seem to have missed it in the Scrypt instructions).

Phil already answered, but just to clarify this is a pool specific setting. For Nicehash it's the "p" option in the password field.

For example, here's how I currently have Nicehash set up as my first pool (with a different receive address):

Code:

stratum+tcp://sha256.usa.nicehash.com:3334#xnsub
18wQtEDmhur2xAd3oE8qgrZbpCDeuMsdQW
p=0.3282

The above 0.3282 number works out to about 5% over the current SHA256 earnings. If Nicehash falls below that, it appears as dead to the miner and the miner switches to the next pool.

The pain in the ass part is that they don't allow me to specify a percentage. It's only a fixed number. So when there's a difficulty change, I recompute the profitability number and restart my miners with it.

I got tired of computing the profitability number by hand (using a mining calculator) so I now do it automatically using some Javascript in a Google Sheets spreadsheet. If anyone is interested, here's the GitHub page with the scripts:

https://github.com/edonkeycoin/gsbitcoinutils

I'm a little unhappy with the performance of blockr.io though (which I used for the scripts). I might switch APIs if I get pissed off enough.
