I've been contacted to help with the escrow for this. It will be very simple to understand and to get involved. The XYY team is to keep a list or website of all investors, the amount of BTC they have invested, their XYY address and a return BTC address in case of refunds.
Everyone will get assigned one address, all you have to do is verify that your address is in the list which I have GPG signed.
Here is the list: http://pastebin.com/r2WJMX80
For the sake of security of everyone's coins, refunds will only be processed AFTER the coin has failed to launch, at the same time. This will be a "cold" wallet, that's why.
No refunds will be issued for investors who change their mind. If you are not sure, do not send. If you send, you are committed and you will receive the proportional amount of XYY as indicated by the developers and website.
If the coin fails to launch in a satisfactory manner all BTC will be refunded back to their owners, less any transaction fees. (Usually 0.0001 per 1000 bytes.)
This is my escrow thread if you want to do some research. https://bitcointalk.org/index.php?topic=234939
Any refund, will be sent to the address that you designate in your account on the ICO website.
I will charge an appropriate fee on the amount of BTC collected by this ICO, deducted at the time I send the funds to the dev.
I will send the BTC to the XYY devs only after the coin has launched, the wallet is working, the investors have received their XYY, and the XYY network has reached at least 120 hours in blocks. I think this is fair, if the coin is 5 days old and everyone got their XYY, then I can release the ICO BTC funds to the devs.
For investors, what you could possibly lose is the time any coins you send until launch. This means your BTC are stuck until then.
For the XYY team / developers, you don't get anything until after 120 hours.
I am not responsible for any coins sent anywhere except the escrow addresses in the list.
