1:55 — “Right now, 25 bitcoins are generated every 10 minutes. This rate will halve every 4 years until the final bitcoins are created in 2140.”

I’m going to nitpick those time frames because they are approximations. The detailed truth is that bitcoins are created whenever a miner solves a block, which may be more or less frequent than 10 minutes (but the network periodically adjusts the mining difficulty to make solving a block take 10 minutes on average). Also, the bitcoin reward is cut in half for every 210,000 blocks solved, which has taken about 4 years in the past. But it may take less than 4 years in the future, especially if more and more computing power is put into mining bitcoins.
