Hal Finney

"Bitcoin seems to be a very promising idea. I like the idea of basing security on the assumption that the CPU power of honest participants outweighs that of the attacker."

"I see Bitcoin as ultimately becoming a reserve currency for banks, playing much the same role as gold did in the early days of banking. Banks could issue digital cash with greater anonymity and lighter weight, more efficient transactions."

"Running bitcoin."

"The computer can be used as a tool to liberate and protect people, rather than to control them."

"For Bitcoin to succeed and become secure, bitcoins must become vastly more expensive."

"Since we're all rich with bitcoins, or we will be once they're worth a million dollars like everyone expects, we ought to put some of this unearned wealth to good use."
