'the limit of 21 million bitcoins[e] will be reached c. 2140' - nope - way sooner!
Section 2.3 'Supply' states (as of this writing): 'The bitcoin protocol specifies that the reward for adding a block will be halved every 210,000 blocks (approximately every four years). Eventually, the reward will decrease to zero, and the limit of 21 million bitcoins[e] will be reached c. 2140'. http://www.howmanybitcoinsarethere.com indicates that, as of this writing, ~18.9M Bitcoin have already been mined. If you stand by that statement, it would be good to show some math indicating how that could be true given the rate of bitcoin mining occurring. If you do not stand by that statement, then change it to something you stand by.

BTW: My take is that a better measure that years should be processor cycles - to account for the change in the amount of hardware dedicated to mining.
