Do not leave all or large amount of your coins in exchanges.
1. Secure. (We have seen some cases)
2. (Now hold in the wallet) Invest in karmashares.
3. Market moves more easily.

FXBT, an exchange in china, just shut down...
seems like a new one shuts down every month or so...
though it might be nice to have Karma on BTER, the future of Chinese exchanges (or any exchanges for that matter) is in doubt.
If you are going to use exchanges as a quasi banks then at least spread the coins out across multiple exchanges so you don't lose them all if one goes down.
I'm just posting this as reminder to keep the message in the back of peoples minds.
If I have a substantial position in any coin I usually don't keep more than 30% on any given exchange.
