What’s the best way to get a terugwedstrijd when wij mine Bitcoins? Should wij mine on our own, mine with a puny pool or mine with a large pool? How much difference does it truly make?
Whether wij want to be a gambler or an investor is indeed a question of how much risk wij’re ready to take, but what are those risks and what are the odds of success?
Kicking off Thoughts
Before wij can look at the odds of getting a particular terugwedstrijd wij need to establish a few commencing conditions. Let’s assume that wij’re programma to mine using hardware that, at the outset of our mining, is able to hash at 0.01% of the total global hash rate. If wij have 120 PH/s of hashing then that means that wij have 12 TH/s of hashing hardware, but if that global rate wasgoed 600 PH/s then wij’d need 60 TH/s. The actual numbers don’t matter tho’, just the percentages.
Wij’re going to assume that the network is expanding at 1% vanaf day. For most of 2014 it has bot above this but the trend is generally downwards and wij need to assume something. At 1% vanaf day then overheen 6 months (approximately 183 days) wij’d see the global hash rate increase by a factor of 6.177 by the end, so our 0.01% of the network is only 0.0016188% after the 6 months. Wij’re not expecting to add fresh capacity spil wij go tho’, so wij only have the hardware that wij begin with.
Bitcoin mining is very erratic (see “Hash Rate Headaches”) so it’s not effortless to calculate how our mining will progress so instead I built a Monte Carlo simulator. The results introduced here all come from that simulation with 10M simulations of each screenplay to ensure that the gegevens is well smoothed.
Let’s begin with the simplest case. Wij’re going to assume that wij’ll use all of our hashing capacity to mine for blocks on our own. What might wij expect?
The chart shows 15 difficulty switches (6 months). It plots the cumulative probability of achieving a particular BTC prize. 50% of miners will achieve 32 BTC or less at the end of the 6 months, while 5% will receive nothing at all! It’s not possible to get smaller amounts ter this time period by solo mining so that’s why there’s a discontinuity te the graph at the commence. 10% of miners will actually receive 65 BTC or more.
The gambler te us might be attracted to the potential for high prizes, that part of us that wants to be an investor however is most likely going to look at this graph ter horror!
Mining With A Pool
The easiest way to mitigate some of the risk is to join a mining pool. Let’s disregard pool fees or anything that doesn’t just give an equal share for hashing capacity provided to the pool. What might the same hardware achieve when run this way?
Our gambler self may be disappointed to see that the potentially large payouts have vanished, 10% of miners will achieve 44 BTC or better. Our, more rational, investor self is very likely much happer however spil only 10% of miners achieve less than 26 BTC. The elementary exercise of merging with a pool that has 10x the total mining capacity has made a giant difference to the variance of the mining prizes. Our 50% prize point is higher too (the chart shows 48% to keep things simpler)!
What Are The Effects Of Using Larger Mining Pools?
Now that wij can see the reduction ter variance from using a mining pool wij truly need to ask questions about just how much does the mining pool size switch the statistics. Ter order to do that wij need to consider a few different ways to deploy our hardware.
The following graph shows a much narrower span of BTC prizes. It also shows the effects of mining spil part of a pool controlling 0.1%, 1%, 10%, 25% and 50% of the global hash rate. That last one is sure to be controversial spil a pool with 50% of the hash rate is deemed to pose a potentially serious risk, but rational miners have bot keen to participate te such pools. Just how good are the reasons to do so?
The very first things to notice are just how bad the solo mining and 10% membership of 0.1% pool now look! The larger pools are certainly more attractive to anyone seeking predictable comebacks.
Mining Pools Are Here To Stay?
Te a simpler world the Bitcoin mining network might only be expanding very leisurely and miners could attempt to permit time to sleek out the effects of mining variance. Te practice however, spil the network expands and the ever-increasing difficulty consumes the usefulness of any current hardware, then best known way to avoid the vagaries of random mining behaviour is to use large blocks of co-ordinated mining. Solo mining and mining ter petite pools is a strategy for gamblers, not investors.
Arguments may rage regarding the risks posed by large mining pools and their tendency towards centralizing our supposedly decentralized network, but it seems very unlikely that they will be disappearing any time soon. Any proposal to eliminate them will have to address the punt of variance if it is to build up any sort of widespread acceptance.
