I thin that pizze is the most expensive pizza in the whole history and can have the world record, I am not sure what the buyer thinks about it now

Why you are not sure? He already explained what he think, you see that if you read the thread. If you don't want to read 72 pages here you can see Laszlo's last posts.

I spent it all on pizza long ago: https://blockchain.info/address/1XPTgDRhN8RFnzniWCddobD9iKZatrvH4

3-4 years ago there were less than 100 people frequenting this forum, and I was pretty happy to trade 10,000 coins for pizza. I mean people can say I'm stupid, but it was a great deal at the time. I don't think anyone could have known it would take off like this.

Thanks for the kind words guys.

The pizza thing was a lot more popular than I thought so I made good on as many trades as I could. Other than a little bit of single digit change, I spent everything I mined. As you all know, the difficulty rises to adjust to hashing power, so eventually the mining wasn't worth it for me.

GPU mining BTC in 2010!??

As far as I know I was the first to release a GPU miner. I contributed the hash meter back then too, that's what the screen shot was all about. I used to maintain the Mac OS builds but others have taken that up now. It was a fun project and I learned all about OpenCL. I can't find the thread on the forum anymore but you can find it in my web dir ( http://eclipse.heliacal.net/~solar/bitcoin/sha256.cl ). That was back in May 2010. Maybe there were other people who were doing it in private too, though. For a long time I had been looking for a reason to learn how to write a shader, and this was a great project for it. The way I looked at it, I was helping out with an open source project, and I was making pizza with my code.

You guys will laugh now but I mined everything with an nvidia 9800 GTX+ on Mac OS (hackintosh, another scene I used to help out in). I ended up getting 2 AMD Radeon 5970s with the bitcoins I was mining, but at the time, the OpenCL libraries from AMD and nvidia both were really buggy and I never got it to work right on more than one GPU. The same code that would work on the nvidia on linux wouldn't work on windows and vice versa. I was trying to make a generic OpenCL miner that everyone could run on all 3 platforms, and I spent months tweaking different kernels for each GPU, but I was also working two jobs at the time and so I never finished it. I ended up just leaving bitcoin on the back burner for a few years, then it exploded and people started asking me about the pizza trades. Every time the value goes up on exchanges, people email me asking me to comment on it, but really there isn't much more to tell than what I explained here.

This is the old GPU mining release I made for Mac OS, probably won't work anymore though: http://eclipse.heliacal.net/~solar/bitcoin/Bitcoin-MacOSX-Intel-svn-75-opencl-2010-05-10.dmg
