Dunno, if you buy at 20% markup on exchanges, you're not using the right ones. Even Cex.io with 3.5% credit card fee is much better than buying from Ebay. And the problem about Ebay is not exactly buying, its selling.

People can buy from you, mine for a while, then file a claim and return the miner because not as advertised etc.

If you buy Bitcoin on Coinbase it can be even cheaper.
Personally i pay a flat 1$ to deposit fund there (and its instant). Then if i buy on the exchange, as a maker, i pay 0% fee. So you could buy a couples of S5's at 1$ markup. Even if you buy only one, this is light years better than 200$+ on Ebay.

I have 3 S5s. A few days ago one of them starts beeping a single beep at approximately 15 minute intervals. The hashing is still fine so does anyone have any suggestions as to what is happening?

Thanks

I don't think that it is excess heat. I use compressed air to clean them regularly.

Well offer me up good alternatives

Yup, kano is one of the best pools out there if not the very best. They have great luck %,  great payments and they're just good. I point all my miners to kano unless ppc rises above btc which it occasionaly does for a few hours.
Ecoining dominates peercoin by finding 60% of blocks, but personally I prefer stratum+tcp://stratum.d7.lt:3333
They have a pretty good pool, only thing they need is more hashrate

yes there are a few but generally multipools arent very good because you may mine with the coin is up, but the pool auto sells those coins so it may sell them cheaper then you would want. plus i think the bots just dump the coins in the bids so if they have many miners the price goes down as the coin is mined.



here is a link to a few

some dont work anymore.. :/

i dont think such a pool exists.. NH is nice because you can often make above btc value per GH, but you arent actually mining for yourself. you just get paid what the site is making on rentals.

also NH jams up the s5s. so if you put it as the first one and your price gets met for a few minutes, you may have to restart the s5 to get it to start mining again once it goes lower. mine just sat idle.
they have special firmware for the s5, but its outdated and it has that internet loss bug that stops the fans.. so if you lose internet your s5 may or may not blow up..

what i been doing is mining DGC for a few days, get about 500 of them.. then switch to PPC..
it takes awhile to dump 500 DGC on bittrex because you cant just throw them in the bids or the coin will crash. figure out what the good profit point is and stick there, just make asks and leave them.

PPC hit a spike on btc-e today, so i sold mine for a nice profit of almost 50c each..


edit, seems bittrex also had a nice buy spike and my dgc sold.. nice..

i do like the idea of NH.. i do not like or support their 3% fee..
they charge both the miners and the buyers a 3% fee.. so they take 6% off the top.

its really greedy.. and its NO risk to them, as they get paid directly from the buyers.. they dont rely on finding blocks like normal pools do.

they should really not charge a fee for the miners at all.. as the miners are supporting their site.. which doesnt always turn a higher profit then btc directly, so lots of times miners are mining at a loss.

I thought you had to use the NH firware to set your miner up for rental at their site?  I've thought about setting mine up as a rental but I didn't want to use their firmware so I passed.
