I'm sure Bittrex would provide escrow for a reasonable fee. Either that or find a trusted forum member here, like Tomatocage, to act as escrow.

Currently the donation address has a little over two bitcoin-worth of coins and is listed as being the 8th richest address. Given that you're only on two exchanges, I'd wonder what risk there is in the holders of the remaining five richest addresses cashing out at some point and dumping this coin's value down. It would make sense for you to nail down the charitable aspects of your project and actually show some charity being performed, otherwise you're just-another-clone-coin and the longer you delay in actually being charitable, the greater the suspicion that you're not.

You are marketing an altcoin through association with the name of a Berlusconi, the idea is for his family wealth to influence the charity you are intending to do in a positive way, not simply to keep talking about day-trading profit while keeping a 'charity' address with a couple of bitcoin's-worth of value in it as though that's going to accomplish anything.

It's not like you are utilising the coin technology to deliver the charitable funds, no, they'd still need to be sold on an exchange for BTC and then for fiat currency in order to purchase the things you say need to be supplied to the needy children.

If, however, you had the backing of a company that actually put together 'care packages' for these needy children and this company accepted your coin as payment for these packages and could receive donations directly from the people who hold 'CHILD', you wouldn't need a centralised collection point for this coin.
