The only limitation on bitcoin at the moment is the amount of shops and stores that accept them. Its a bit of a catch 22 scenario, shops are reluctant to accept a volatile currency but without the shops bitcoin community wont expand
I would love to be white listed because.......Im not new bitcoins, I not even new to this site. I am what you would call a professional lurker, but the time has come for me to say good bye to my lurking carrier, and graduate into a full-on member of the bitcointalk community. There are various threads that offer a wealth of information that I feel I could both contribute to, and learn from.
I'd like to add Trust no-pc either. I don't know how, but in the last 3 o 4 days somebody cracked my e-mail password and requested a password recovery from Deepbit, then changed the Reward Address... I've lost almost 1BTC, until I realize what happened.
Therefore, don't trust any other pc than yours, and eventually check your payments address...
How did they get your password? Brute force? Keylogger?
