substrata is right about 59.644201 premine.

I'm not a developer, but I was one of the testers. I mined 60 blocks in testing few hours before launch, deleted the wrong, alpha-testing chain and joined network after the launch with higher blocks and in fact taken over first 60 blocks.

I have only 130kh miner so I was shocked for my "luck".

If I would just stay connected before launch, dev's would see my blocks and we would delete blockchains again.
Its all my fault. I'm a crappy tester, sorry.

 Unfortunately I sold them.
I'm in the proces of buing them back [at much higher price], I will destroy them, or give it as a bounty for an exchange. Its for you to decide. Luckily for me I got some donated for this cause, so I would not be totaly broken.

BTB goes to history books not only as a first ALT to brake 1BTC price level, but also the lousiest premine ever made, premine that made me broke, not rich... I'm an idiot.
