First - amount of bitcoins, including less-than-one bitcoin parts (21 millions * 10^8 = 2,1 * 10^14) is not enough for all of the world.
(at now its about $5*10^13, including cents it's about 5*10^15 pieces).
So for future, if bitcoin will become the world's primary money, we will need more parts of those.
It is possible to make smaller parts of bitcoins?
Second - what if some governments will try to stop this idea? I already read about crypto-strength, but how is regulating "difficulty" of bitcoin mining done? Is it regulated by some algorithm, or by a switcher in some office?
And, to make the question somewhat wider - will bitcoin work, if the developer's office is successfully bombed tomorrow?
If these questions will be solved, I think Bitcoin is best idea for keeping my money.
P.S. Sorry for my English. If i made some mistakes, will be glad to hear where i did it.
1. Yes, with a fairly simple modification of the protocol we can allow bitcoins to be divided to smaller parts.
2. Governments might, if they so choose, prevent people from openly using Bitcoin, but they can't prevent it from being used at all.
Difficulty is regulated automatically by the network via an algorithm.
Bitcoin is an open source project. It doesn't have a
developer, it has several developers all over the world, and anyone can become a developer if they so wish. So Bitcoin will survive a manhunt against all current developers.
Look at my quotation of your post, I've corrected most of the English mistakes.
