aus dem "Humble 2K Bundle". Ich hatte die Spiele bereits und keiner meiner Freunde kann sie brauchen. Hat hier jemand Interesse und würde paar Bitcents springen lassen? Hatte so an 0.02 für Enemy Unknown, 0.01 für Bioshock 2 und jeweils 0.005 für die anderen X-COM Teile gedacht.

Anmerkung: Das Schenken bei Humble Bundle Steam Keys geht nur per link zu einer Seite von Humble Bundle auf der ihr dann euren Steam Account angeben müsst und per "Knopfdruck" das Spiel direkt eurer Steam Library hinzufügt. Desweiteren bekommt ihr das Spiel NICHT als doppelte Kopie in euer Steam-Inventar, wenn ihr es schon in der Steam Library habt. Auch ein erneutes weiterschenken per humble Bundle Website geht nicht.

Hier noch der Link zum Artikel auf der Humble Bundle Website der erklärt wie das schenken abläuft: https://support.humblebundle.com/hc/en-us/articles/202712460-Gifting-Steam-Keys

Well,

today I found out that at least in Bitcoin-Core there are cases in which the client does NOT automatically deduct a fee from a transaction (Before today it always did for any transaction I made). My guess is the rationale behind this is that such transactions aren't stressing the network much and thus should be handled for free. Obviously though the democratic vote of the miners is: Add a fee or GTFO. Which means such transactions are punished by taking ages to be confirmed.

So my question is, why do we need to manually force Bitcoin-Core to apply a fee to EVERY transaction regardless of size and number of coins? Imo that should be default behaviour. Slow transactions are one of the biggest flaws of Bitcoin anyways and the current default settings do not exactly help the situation.

Saying bitcoin transactions would be free of fees is a lie either way (and this lie is overlooked by most only because the fee is an extremely small amount of money if converted into FIAT currencies). And come the day that block rewards hit 0 (all bitcoin are mined) the fees will rise substantially and may even exceed what is charged by "traditional" payment providers.

Hi,

you find me somewhat confused right now. I just made a payment using my bitcoin-core wallet. I put in the address and the desired amount of Bitcoin to send and was expecting to be informed about the TX fee and having to confirm when clicking "send" as it always did up to now.

Well the TX-Fee dialog did not appear and the transaction was obviously sent out without fee.

I activated coin control and played around with it for test and apparently, when you use more than 1 address as input and hit less than 1 KB transaction size it doesn't deduct a fee. Is that behaviour intended?

Will my transaction be confirmed?

Wie der Titel schon sagt suche ich zwecks Aufrüstung meines Gaming PCs günstiges gebrauchtes Ram. Gesucht ist:

8 GB Kit (also 2 identische 4GB Riegel) DDR3-1333 non-ECC Ram.

Hersteller ist mir fast egal. Einziges was ich nicht will ist Geil Ram. Ich hab mal bei nem PC Produzenten gearbeitet und weiß was die für'n Schrott produzieren.

Bevorzugte timings: CL9-9-9-24 (das sind die des bereits vorhandenen G.Skill 4 GB Kits)

Bezahlung ausschließlich in BTC. Meine Preisvorstellung läge bei 0.12BTC

Gerne mit Escrow.

I just wondered that. I see it increase and know it somehow makes mining harder to keep the blockrate at 10 minutes per block.

But how does it do it?

Does it

a) make it harder to create the actual hashes thus making the hardware take more time to create them?

or

b) increase the total number of hashes that can be created thus decreasing the percentile of the hashes that are valid for the current block?

Related question: Can hardware become outdated because it it will not be able to create hashes anymore as difficulty rises? Or does it's usefulness purely stem from the number of hashes it is able to create per timeframe?

So I tried to setup solo mining just for fun.

Bitcoin-core is running as sever and BFGMiner does connect, but there are no shares accepted and BFGMiner keeps repeating "Pool 2 isn't providing work fast enough" several times followed by "Pool 2 has catched up to new block".

What am I overlooking/doing wrong?

Hi, didn't know which section to fit it best so I put this question here as it is interesting for Beginners as well.

I just saw the announcement of Bither in the Project Development section.

And one function is particularly interesting: The ability to setup transactions in the hot wallet and sign them from the cold wallet without a need to bring the cold wallet online.

As I don't have a second phone and mainly use bitcoin from home rather than on the go I would be interested in mimicking this using my old unused notebook as cold wallet and my PC as hot wallet. Is there any wallet software that allows for doing that?

As the title says:

Is there any way to find out how many different pools/solo miners have solved blocks during a set amount of time?

Is someone already montoring it? And is this number declining or rising?

Hi,

habe das schon in allen möglichen anderen Foren gepostet, weil google ausnahmsweise keinen Rat wusste:

Mein Sidewinder X6 Keyboard hat seit einigen Wochen Ausfallerscheinungen:

Die Tasten Unterhalb von "ASD" und links von "B" und "Space" reagieren nur noch bei deutlich erhöhter Krafteinwirkung.

Hat einer nen Rat woran das liegen könnte und wie man's beheben kann?

... would difficulty drop down to a point where i solve a block every ten minutes? If yes would you guys consider doing it for an hour or so? I'd sure return the favor.

As the title says:

I as probably many others have several receiving addresses to keep track of which coins came from where. And recently the question came to mind: If I wanted to cummulate all the coins in one of my addresses would I be able to do so? And what about the transaction fee for all those small transactions of the coins that come from faucets?

I just got my two Antminer U2 and followed this guide to set them up, but ran into a problem:

Wether i use a batchfile or start bfgminer manually without options and setup in the program bfgminer's window will disappear after a short while of mining. The process though remains active as i can see via the taskmanager.

What culd be causing this?

Details: Win 7 64 bit, BFGMiner 3.10.0 64 bit, mining on eu-stratum.btcguild.com. The two AMU's are connected directl to the PC via the onboard USB slots using lengthening cables. So far i only ran with default clock (x0781) via batch (since you cannot set the clock in bfgminer itself I suspect it uses that setting aswell when I just start BFGMiner and setup the devices in the manager).

could underclocking be the key?

Hey folks. I am currently toying around with ideas for a bitcoin driven gaming/gambling website. The game side of the thing would be like this: People play for a placement in a leaderboard and pay some mBTC to play, the best placed players after a week/month get paid out of all the entry fees of the game minus a small amount to cover site costs (something like 95% of the entry fees get split up 50/30/20 amongst the top three).

Now I have some questions regarding the technical bitcoin related side of things:

I figured that since having to wait for confirmations everytime you pay the fee to start a game would be inconvenient I'd create an address in the site's wallet for each member that can be filled by the member with coins to play with. Every game/leaderboard has it's own address in the wallet aswell. Since they're in the same wallet I could safely let the game start without waiting for confirmations of the transaction from the member address to the game address.

Does that make sense?

Further and more to the actual point:

Since the above described design would involve a heck of a lot of addresses, what wallet software would be best suited as the basis of the backend?

Should one run such a service on a windows or a linux server?

What's the best way to setup such a service's bitcoin backend: Wallet and website on the same machine or on different machines at different locations?

Thx in advance for any helpful link and answer.

@Mods: I wasn't sure wether to put this into the project development, service discussion or technical support section, pls feel free to move it accordingly if i made the wrong choice.

Hi, quick question cuz I am too lazy to search:

I am using bitcoin-qt eversince as my wallet. I have setup a seperate receiving address for each faucet/ptc/offer site I use to keep better track of payments.

Is there a way to show the balance for each address seperately?

Thx for anything helpful.

I'm sitting here shocked by myself.

Let me elaborate:

I am currently playing the game Mechwarrior Online, which has nice stats pages in your profile on their site. Yesterday I had the idea of making a signature that would show part of the data from those stats pages in a realtime fashion as part of an image.

So I started thinking about how to achieve this and since I studied Computer Science (though without getting a degree for reasons) for 8 years the answer was quite obvious: A server side script that gets the needed data from the stats pages and puts it into the image upon request. Easiest way to do obviously would be PHP, which I never really got around to learning, but I was allways fast to pick up syntax and beyond that PHP is just a scripting language like any other.

Now I am literally sitting in front of my desktop having tutorials and code examples opened. And instead of starting to code I am seriously considering putting up a bounty on these forums for someone else to code that stuff for me.

Let me get that straight one more time: I have the understanding, information and means to do it myself. And I am thinking about paying someone else to do something I'd be able to do myself without a problem.

Ok I answered the question. I AM fucking lazy.

The way I understood everything with PPLNS provided your pool is able to find at least one block per N-interval, it does not matter which pool you mine on as far as results go because the value of a block is set.

Or said otherwise: The higher your hashrate is the more preferable become smaller pools because that increases the value of the shares generated by you in relation to the shares generated by the pool in total.

That said amongst the PPLNS pools the one with the lowest fee is best as long as N is big enough to guarantee at least one block find per round.

The second most improtant decision criterium then would be how many faster miners are in a pool, competing with you for the leadership in shares created per round. The less the better.

Does that seem about right?

Hey folks.

I've noticed that whenever I make "larger" (like >0.01) transaction I have to pay a "small" (0.0015+) fee which "is spread amongst the nodes veryfiyng the transaction".

My questions are:

How can I become such a node myself (using bitcoin-qt)?

Is that transaction fee avoidable?

Hey folks.

I recently stumbled about bitcoin-services.co.uk. Particularly the "earn free bitcoins" part of the site. It basically is a click ads, watch vids, do surveys, register for sweepstakes kind of thing, with very good payout. The points I gathered should be worth about 0.04 BTC according to what the description says. But the problem is that I am waiting for payouts for about 5 days now, while the site says payouts would take 24 hrs.

I emailed them already but got no answer yet. Also their support site says there'd be a live chat but that's nowhere to be found.

Is anyone here that used the site and received a payout?

Should I just abandon the site and write it off as defunct?

Hey folks.

I'm a newbie (obviously). I just stumbled upon bitcoin two days ago when seeing a TV report about it.

I read into it an found it an interesting concept. Since I have this fabulous, yet a little outdated gaming rig I figured I'd give mining a shot. So I setup the original bitcoin client and guiminer and started mining in the BTCGuild Pool with my 2 5750s.

My Hashrate is at 300 MH/s, which nets me roughly 0.015 BTC per 24 Hour period. I calculated it through, since my rig is running 24/7 anyways, since I do work on it besides gaming, I am in fact making a slight profit at this rate provided the BTC exchange value stays roughly where it is now or above. The great thing is, that I had no initial costs, because I had this rig already.

Still my questions are:

Are there pools that are more profitable?
How likely is BTC to at least maintain it's current value?
At that rate, would you continue to mine or would you suggest getting BTC by simply buying them, working for them, or selling stuff for them?
