as we all know that bitcoin was designed to be a decentralized currency. Yet people have pointed out that 50%+ computing power is owned by only few mining pools. It really hits me hard when people still claim bitcoin as a decentralized currency, especially after yesterday's unfortunate Mtgox incident. Yes, Mtgox surely did a bad coding job. But please really think about who were the attackers?
In order for such faked transactions getting included in the blockchain fast enough and "lucky" enough, I assume it must have something to do with those "centralized" groups of people, at least.

Bitcoin is so decentralized that if every human being on earth were suddenly vaporized in a nuclear holocaust except for the guy in the photo above, who currently has .003 bitcoins on his computer, the entire bitcoin ledger would be safe.
Did anyone notice the "outdoor toilet" next to the wooden steps.
There's also toilet paper on the second step

Now that's getting in touch with nature, don't you think?
