Ok this is a pyramid scheme and it will collapse and some people will lose out.

The difference here is that everyone has an equal chance of being on the first few levels of this. I won't open it until 8pm (London, BST) Monday 4th July. Any payment sent before then (above 0.01 BTC) will be returned.

All you have to do is:

1) send any amount you want (+0.01 BTC for the transaction fee) to

Code:

2) Wait to be paid out double what you put in.

People get paid out as usual, in order of joining the game. If the first person deposits 2BTC then they get paid out when the pot has built up to 4BTC, and this continues. The game will run until there has been no activity for a week (if that sounds reasonable).

I'm posting this now so people can bookmark the thread to try and get in first. You can also get any of your friends to join to try and make sure as many people get paid out as possible.

Another advantage of starting on Monday is that if there are any issues that people want to discuss, we can.

I will post all activity on here and when you get paid it would be great if you could post to confirm.

UPDATE: Here's the spreadsheets:
