Quote from: the slick Bitcoin video
"The anonymous creator put 21M of them in the ground, but with each new batch of coins that's unearthed, the program's code automatically makes it harder to solve the next problem, thus timing out the supply."
It doesn't become harder, the reward is less.
The "new batch" would be the halving of rewards every 210,000 blocks - every four years.
Mining becomes more difficult, but to adapt to miner hashrate, not to affect ultimate currency supply.
How do you obtain Bitcoins according to the video?
Quote
"The most popular way is from the Japanese site mtgox, which acts as an exchange. You can set up a connection to your bank account, convert real dollars into bitcoins, and store your coins in a digital wallet."
"real" dollars? Mtgox is not a wallet.
