Hi all,
Thanks to the awesome people over at Blocktrail, we've been given a ton of information on mining pools that have mined blocks, since day 1 of the bitcoin protocol on 3rd January 2009. I'll be writing up some retrospectives on this a little later, but to start off with, I have the figures January 2015.
Some more information, and the data behind it is available at
http://bitcoinsinireland.com/bitcoin-mining-rankings-january-2015/ Top level figures (in Euro)
6429 blocks of 25 bitcoin each, a total of 160,725 coins mined, worth €34,417,651.5 when using the Google bitcoin price at time of publication (€214.14 / 15/02/2015)
Enjoy!
Jamie
