Bitcoins have been a very hot topic recently; similar to what we have done in other blog posts, we aim here to understand fashionable financial/economic phenomena through data and analysis.
Bitcoins started more as a geek hobby to become a real investment vehicle for many speculators/ investors. With this craze, the value of Bitcoins at increase more than 10 folds over the past 3 months. Wondering how to best enter the franzy, either by buying Bitcoins or by mining Citcoins we did a economic analysis of the Bitcoins mining economics. We found that based on the current situation, miners must invest roughly 40$ to mine a Bitcoin while they can be sold in the market for close to 1000$, a 25 folds gain. Inaddition, projecting these results in the future, we found that it will take untilk 2015 for the cost of Btcoins mining to reach the current 1000$ price level and finally close the arbitrage.
Buy or Mine
For people interest in getting some Bitcoins, there are two different avenues: you can buy them on one of the exchange market or you can mine them. The concept of mining is challenging to understand for many but basically Bitcoins are created every day at a rate of about 25 per period of 10 minutes. People with the right equipment (i.e. hardware and software) and technical ability can join the other miners to “mine” those newly created Bitcoins.
Results and observations
Our quarterly financial model of Bitcoinc mining is based on most recent inputs available, see below. It's divided into 3 sections: the financial inputs / economics, the technical parameters and the mining cost calculation. The cost per Bitcoin line represents the total costs associated to mining Bitcoins for a well performing miner.
Check the some of the detailed calculation by looking at my new post of the Revenues Generated by Bitcoins mining.
- Current mining costs: It costs a miner roughly 40$ today to mine a Bitcoin, this represent a 25x gain for miners
- Exponential cost increase: The cost would be in excess of 10,000 by 2017.
- Equilibrium reached in 2015: The costs of mining Bitcoins will converge with the current price in year 2015 (around mid-year). Between then and now it seems to make a lot more sense to invest in mining rather than buying Bitcoins
- Hardware is the big cost drivers: The key driver of costs for miners is hardware; currently energy represents only a fraction of the total mining costs. This is due to change in the coming 5 years
- Mining is the clear choice: All results are totally dependent on miners view on price, for now anyone that has spare computing capacity should mine Bitcoins. Going forward the arbitrage is likely to close
- Power consumption: Based on our calculations, by the end of 2016 the total processing power on the Bitcoins network would consume a quantity of power equivalent to a small city. By 2018, equivalent to the consumption in Michigan

Model inputs and hypotheses
Find below the input value we have used to create the model, based on our research we strongly believe it's a very good representation of the current reality of Bitcoin mining.
