Registering names wouldn't be a bad idea.

I'm also trying to find other fair ways to generate numbers other than blockchain. At the moment I could do 25 prizes varying from 0.06BTC to 4.0BTC. But it wouldn't evenly distribute chances among block hashes.

For example (Block hash ending in):
0-8 0 - entrant A - meaning 00, 10, 20, 30, 40, 50, 60, 70, 80
9-f 0 - entrant B - meaning 90, a0, b0, c0, d0, e0, f0
0-8 1 - entrant C
9-f 1 - entrant D

This would generate 32 tickets with even probabilities of winning.

I tend to agree with Mitchełł.

The issue of trust and security has not been discussed at all.

If these coins are prefunded with 1 BTC, then are you trusting BTCC with a lot bitcoins.
Not saying that they are intentionally planning a scam (even though it is still a concern) - but the way the private keys are generated, printed and handled should be of the concern of all potentially buyers.
1 BTC is not a small amount.  

Key to success is to be open about how security is handled; how are the keys generated? who handles them? what measures are done for long term preservation of the print? How is it secured that all traces of the private key is removed, hard-drive is demolished after production?

The main concern here is that years from now, long after BTCC cease to exist, the suddenly are funds removed from the coins due to an unauthorized copy of the private key floating around.
Or, you open the coin 10-20 years from now to redeem the coins and you find the private key paper completely deteriorated.  

Back in the days, new manufacturers was given a hard time when introducing new coins due to security concern, especially the higher denomination.

Many new manufactures, handled this problem with the initial trust by introducing coins with small denominations, e.g. 0.1, 0.05 and 0.01.
Here is the coin it self worth more than the coins loaded (with the BTC exchange rate at time of purchase) so the risk of future security is minimized.
Other manufacturers handled this by releasing the coin as DIY.

When that is said, the coin looks great and the concept of funding with virgin coins are brilliant.  

Bump

I'll release a list of all the prizes.

Sweet.... I will set it up.

I would also prefer unfunded..... I could afford more than 1 coin then.

Thanks.

I have intimate knowledge of someone you can get one from.  Oh, wait, you can close the thread. 

Now that looks great.
This is how BTCC should have started.

I've won! Thanks MJ for making my first raffle a winner!
