Ok thanks gents.

Double private keys are possible as I expected.
Didn't know there were so many sharks listening for known public addresses (that link to easy brain wallets)
Crazy.

Ok thanks but ...

1:: With encrypting a private key, do you mean something like this:

- encrypting your computer filesystem or hard drives
- Running some algorithm on the private key that only you know, and you remember
- Childishly reversing the order of the key, and remembering that you wrote it down in reverse (and the thousands of other things that come to mind)


2:: Does every miner in a pool, while it is verifying transactions, tries to bundle transactions and secure them into a block?
Or is only 1 block / pool suggested for acceptance by the network (every 10 minutes) ?

echo "Hello World"    (first post)

Got into Bitcoin just recently. Been reading a lot about it, but I am convinced that I'm only seeing the tip of the iceberg right now. So much to learn.
I would like to understand everything about it, step by step. And even if I am no crypto expert right now, to say something, I would like to understand it all.

So to get there I have some questions/doubts/statements you guys can help me with. I am no noob wannabe hacker, I just want to understand it, and FEEL SAFE

1: If I would have your private key, I could just import them to my wallet and steal your funds

2: Password protection of a desktop, mobile or paper wallet is only to protect the computer, phone, or piece of paper. The actual private key is never password protected

3: If I would be able (I know it's not possible) to import all the private keys in SHA256 to my multibit client, or whatever, I would have access to everyones wallet

4: What happens if 2 people create the same brain wallet? Are you expected to check blockchain to see if the account has 0 transactions?

5: Making money with bitcoin, mining bitcoins, is nothing more than joining a mining pool and helping to bundle/verify transactions into a block and securing it. If your pool has won, you get a small fee wich is how new bitcoins are created.
