If it gets tiresome working with small numbers, we could change where the display shows the decimal point. Same amount of money, just different convention for where the ","'s and "."'s go. e.g. moving the decimal place 3 places would mean if you had 1.00000 before, now it shows it as 1,000.00.
Right, the difficulty adjustment is trying to keep it so the network as a whole generates an average of 6 blocks per hour. The time for your block to mature will always be around 20 hours.
The project needs to grow gradually so the software can be strengthened along the way. I make this appeal to WikiLeaks not to try to use Bitcoin. Bitcoin is a small beta community in its infancy.
In this paper, we propose a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions. The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.
In a few decades when the reward gets too small, the transaction fee will become the main compensation for nodes.
Total circulation will be 21,000,000 coins. It'll be distributed to network nodes when they make blocks, with the amount cut in half every 4 years.
first 4 years: 10,500,000 coins
next 4 years: 5,250,000 coins
next 4 years: 2,625,000 coins
next 4 years: 1,312,500 coins
etc...
When that runs out, the system can support transaction fees if needed. It's based on open market competition, and there will probably always be nodes willing to process transactions for free.
