* To fully mine the very last whole bitcoin it will take approximately the same time of mining the first 20,943,044 bitcoins (i.e. about 34 years)

* According to estimates, bitcoin will reach its final coin figure sometime in 2140.

* At the time of writing, more than 3 out of every 4 bitcoins that will ever exist have already been mined. Current block height is 517369

* The total number of bitcoins, as mentioned earlier, has an asymptote at 21 million, due to a side-effect of the data structure of the blockchain - specifically the integer storage type of the transaction output, this exact value would have been 20,999,999.9769 bitcoin.

* The first 50 BTC, included in the genesis block, cannot be spent as its transaction is not in the global database.

* The Bitcoin block mining reward halves every 210,000 blocks, the coin reward will decrease from current 12.5 to 6.25 coins.
