Glad crypto-games is handling this situation better than many online wallets and this is what everyone expected from one of the most trusted crypto gambling site. But still we can see a huge panic withdrawal from the bankroll.
While nobody should have to worry about keeping their funds on CryptoGames during the fork, having your coins in addresses you control the private keys to is the better option.
Someone who eg wants to sell their BCC as soon as possible might prefer to handle things themselves and not be subject to the dirstibution speed of CG.
On the other hand, it's a very comfortable way. Keeping your funds on CG means you can get BCC on an exchange account without having to install a BCC client and import keys there,
as CG is taking care of all those thing. I think that's a good way, especially for those who are new to bitcoin or just not as versed technologically as the average bitcoiner.
