I am trying to evaluate how much one could earn as pool owner/solo miner if bitcoin really appreciates in price. To get a number i try to get a figure how much one mined block generates in for example a month, week, year.

  1. How much fees does one mined block generates actually in a given timeframe?
  2. What percentage of that is from the block reward, and what percentage is from fees?

Let's look at an example. BTC Guild (www.btcguild.com) has about 33k GH/s.

That's about one third of the whole Bitcoin network combined

So let's imagine on average they mine one third of all the blocks. That's 6*24 / 3 = 48 blocks in a day, 336 blocks in a week, and 1440 blocks in a month.

Now assume each block has a transaction fee of 0.5 BTC on average. Now counting only transaction fee's: That's 24 BTC in a day, 168 BTC in a week and 720 BTC in a month.

1) Fees are very block-dependent but recently have normally been in the 0.25 - 0.5BTC range

2) A mined block currently gives 25BTC + fees. From the above, fees are coming in around 1-2% of the total block reward

  • Thanks for your contribution to my question! On which timeframes are these estimations build? Iam trying to understand how much a pool-owner/solo-miner can earn by fees in a week, month, year. – Aurigae May 19 '13 at 17:32
  • Well that's a different question to the one that you asked. My answers are per-block, but you also want to know blocks per week/month/year. The answer to that is totally dependent on the number of hashes you can get through per second. You also need to know your electricity usage and cost of electricity so that you can subtract that from your income. And then pick an exchange rate. Bottom line: it isn't quite so simple, and there are a number of similar questions and answers which you should read to get an overview of this area. – jgm May 19 '13 at 19:50
  • I still try to figure how much one makes on transaction fees. To get more precise lets say transaction fees at current bitcoin price with 1 mined block in a given timeframe ie 1 week, month, year. In point 1.) you already made a figure, but on what is that based. – Aurigae May 19 '13 at 21:24
  • If you're talking about how much you get in your local currency then translate the BTC to whatever currency you're thinking about. As for where the figures come from, the 25BTC figure is baked in to the Bitcoin system (it halves every four years or so) and the transaction fees come directly from the details of mined blocks within the blockchain (looking at blocks over the past 5 months as representative). The whole 'per week/month/year' thing is totally dependent on your hashing power i.e. how many blocks you can mine in a given timeframe. – jgm May 20 '13 at 6:56

    If I solo mine I earn 0.25 - 0.5 BTC per block mined, as per my original answer. If I run a pool it's up to me as to how much I keep, and up to others as to if they sign up to it. Pools vary in the way that they work but most keep mining fees plus 3% of the block reward, give or take. – jgm May 20 '13 at 12:57

http://blockchain.info/block-index/383911 On blockchain.info you can see the transaction fees payd to the miner. On the sample link Transaction Fees of $ 41.75 have been payd in 480 Transactions.
