Sure... find a block today and get 1BTC.  It also qualifies you for the diff change promo - which could win you another 1BTC.  With the diff change only a few days away, that's not a bad return

I wish our rates were a nice and simple structure like yours - although I don't envy the price you're paying .  Rates here fluctuate depending on time of day, time of year, tier, etc.  For example, in the winter during off hours the rates are relatively low.  During the summer and peak hours the rates are relatively high.

Come on blocky blocky blocky... come out and play with us!

LOL... Buy-It-Now Hosting.  Love it

I've got 8 S3s sitting around doing nothing.  20 A6 and 1 S5 chugging away - the S5 is about to get unplugged, too.  Talk about close... one of my A6 hit a 183G share.

The hardware owners.  Right now they're averaging about 140% of expectations, even after the 3% NH takes off the top.  Oh, and of course NH makes their cut (3% from the renter and 3% from the owner).

If you've got enough hash to expect to hit a block in the next 52ish days, which right now translates into just over 185TH, then statistically you'd have the same earnings solo mining as you would pool mining.

Solo mining is always going to be an all-or-nothing gamble.  Just because statistics say 185T should hit a block before the halving doesn't mean you will.  Then again, you might hit a couple.  If you're mining on a pool, that variance is reduced.  You might earn a bit less than 25 coins, you might earn a bit more.  Chances are real good you'll make close to the expected earnings on a pool.

Pretty sure you answered your own question there...

The part I bolded in your statement is exactly what was just proven incorrect.  If the block reward was not halving, then yes, you'd expect to earn the same if you were solo mining or pool mining.  However, because the block reward is indeed halving, then the math clearly shows you making more by mining on a pool than you would trying to go at it solo.

I for one did not know it was Genesis Mining.  Wow.  I thought their gear was supplied by SPTech - I remember the promo and announcement between the two, and the links to buy contracts right on Spondoolies site.

The R1?  Assuming stock speed of 5.5GH/s... right now it's about 4810 years until it would find a block.  Those are some pretty long odds

2BTC is a bit too big of a bite for me to take.  Good luck, and again, congrats on the upcoming baby

Glad to have helped

Your asking price is way too high.  I'd be willing to do 1.25BTC for both.  I'd pay shipping.  We can use Phil as escrow, no problem.  Also, I would certainly not have you ship across the country to Phil, who would then have to reship it back across the country for me.  My hosting provider is perfectly capable of evaluating the functionality of the miners - they have done so for the 18 Avalons I currently have hosted there.  I don't need the rPi or the cables, I've got plenty, so you could sell those off independently if you wish.

Congrats on the upcoming new addition to your family!

Theoretically, you should make the same amount of coin regardless.

However, theory is not always accurate in practice.  Let's take a look at some numbers...

For this exercise, let's assume you're a hobbyist miner and you've got 10TH of hardware.  Let's also assume that the hash rate of the bitcoin network remains constant (I know this will never happen, but for the sake of the discussion, let's suspend belief for a minute).

Ok.  As of right now you're asking yourself should I take the chance and solo mine, or stick with a pool?  Let's find out.

With 10TH you expect to find a solo block after ~966 days.  At that point in time, the block reward will be 12.5 coins.  There are ~52 days left of 25 coin block rewards.  Your 10TH expects to earn 1.34628BTC in that time.  That leave us 914 days of mining where your expected earnings are 0.01294BTC a day.  This means you would expect to earn 11.82716BTC in that time.  Added together this means you'd expect to earn 13.17344BTC total.

So, assuming everything remains as it is, you'd be better off mining in a pool earning 0.67344BTC more than you would going the solo route.

My pleasure.  Please check out my pool's thread here: https://bitcointalk.org/index.php?topic=1330452.0.  Plenty of people there willing to help you with any issues, or to simply chat.

I look forward to seeing you there.

Thanks for the recommendation spiker777

Wintermeasures, while I certainly echo spiker's recommendation (it is after all my pool ), there are plenty of good options for you out there.  Besides my pool (http://bravo-mining.com), here is a list in no particular order:

bcmonster.com
kano.is
bitminter.com
mmpool.org

You'll notice I didn't include a single one of the big pools.  Why?  For a few reasons.  First, they all use a process called SPV mining.  This is a blight and should be eradicated.  It can, and has in the past, cause hard forks.  It can, and does, produce empty blocks.  Second, they are simply too big.  Too much control of too much hash is not a good thing.

Best of luck, and I hope to see you as a new miner on my pool.

Somebody decided that your S5s were somehow involved in illegal Dark Web activities and shut them down?  Yikes.  Time to find a better hosting provider.  I've heard bitclouder.co does a pretty decent job for our EU friends.  Have you checked them out?

As for the solo lottery thing... that's definitely a hell of a long shot.  Right now with 2 S5s, you would expect to find a block after 4180.6 days (that's 11.45 years).  Statistically speaking, you're far better served mining on a pool, because by the time those S5s find a block, the reward for doing so will be down to 3.125 coins.

The answer is pool.

At current difficulty that S7 expects to find a block in 2032.5 days.  By then the block reward will be 6.25 coins.  You missed the remaining 52ish days of 25 coins per block, and the entirety of 12.5 coins per block.  Even if things remained completely unchanged, pool mining would expect to earn you 0.65 coins until first halving.  Then you would expect to earn 8.97 coins until the next halving and then 1.6 more coins until your S7 would finally expect to hit the solo block for 6.25 coins.

Then it's likely your alternate Berkeley DB is being picked up first in the search for appropriate headers.  Try renaming the other include/lib directories to something the search won't pick up.

LOL... not sure we'd really want that to happen.  Chinese pools represent the vast majority of the network hash.  If the GFW was to go down, they'd be working on one chain while the rest of the world worked on another.  As soon as the GFW came back up, chances are exceedingly good they'd have the longer chain, thus rendering the rest of the world's chain worthless.

Now, if all of those pools, and the hash associated with them, suddenly went dark that'd be a completely different story.

Good luck everyone!  Let's nail a couple blocks

I'm going to assume you downloaded the bitcoin core source to /home/user/bitcoin0.12.1, your db4.8 includes are at /usr/include/db48 and your db4.8 libs are at /usr/lib/db48.  As such, you would execute the following:


As to your second issue, I don't typically build with QT support, sorry.

Hope this helps.
