Suppose that the lowest bid is $14 and I issue an order to sell 1BTC at $10. Do I get $10 or $14? (and the same thing for buying)

I did a really dumb thing. I somehow added my mtgox address as a receiving address in my bitcoin client. What will happen if I transfer bitcoins from my client to mtgox? Where will the money end up?

I tried some of the games in this section and most of them are old concepts adapted to work with bitcoins (poker, lotto, roulette, lottery, etc.). I am not saying they are bad. On the contrary, there are really nice games here with a great design.
But I got myself thinking about a game that can only be played with bitcoins due to its special features and I think I came up with something. I will explain my idea so let me know what you think.

I am a programmer, but I never did anything web-related and I just don't have enough free time right now to create a project like this. If someone really likes the idea and wants to go ahead with it, great. If that someone gets lots of money from 0.1% comissions and wants to give me something, even better But I am not demanding anything. Just wanted to share this.


Now what really matters, the game:

My game is similar to a lottery. Every person will buy a ticket and that money adds to a pot that goes to the winner (or winners). The difference here is that you buy that ticket with your receiving address (unique characteristic of bitcoins). Let me elaborate on that.
Each address has a number that is created by a simple mathematical algorithm. For example, if you assign a value to each letter, you can add all the digits of the address and you will get values from 1 (100000000000000000000000000000000) to 1985 (1ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ). Using this approach, your address is always converted to a number between 1 and 1985.

My game consists of a website where there are periodic lotteries (say once a day or once an hour, depending on the number of people playing).
In every lottery there is a value that determines the winner. Every lottery starts with the value 1. Every participant that enters the lottery must pay 0.1BTC and provide its receiving address. The 0.1 BTC increases the pot and the receiving address increases the value (with the algorithm explained above). If the lottery value reaches 1985, the value will loop and start from zero (1900 + 95 = 100). The winner(s) is the owner of the address closest to the lottery value when time is up.
So if there are 3 players when lottery ends and the value of each addresses is 1023, 456, 908, the prize pot is 0.3 BTC and the winner is the address with 456 (because (1023 + 908 + 456)%1985 = 402).

I picture this game with a clean and simple website that has a counter indicating the current number and time left. It should also show how many addresses are playing right now, their values and the current winner. It also has a textbox where the user can find out the value of his address before playing.


I am sorry for the text length. If you read everything... Thanks I'm looking forward for opinions and suggestions.

So I got by first bitcents in my wallet and I wanted to transfer them somewhere else, but the client says that I must pay a fee of 0.0005 because the transaction is over a file size limit. Is this because the amount is too small, because the bitcents are too recent or because of something else? I have nearly 200 confirmations...

I believe that, from now on, mining will always be barely profitable. Not much more nor much less than that.

This happens because difficulty always corrects itself when there are too many or too few people mining. If it is really worth it, people will get in. If it is not, people will get out. It's a smooth process of self-adjustment.

With time, mining hardware will become much more efficient and people that invest in recent hardware will get more profit than the others, but that will soon be corrected by hardware depreciation.

Am I missing something?

[a lot]

This may sound stupid, but isn't it possible for someone to create a lot of bitcoin addresses and start stealing money from other people? I could make a script that keeps generating new addresses and spends any money that arrives on them... no?
