Thanks
I just use Namecoin-QT. I do not trust leaving any quantity of anything at BTC-e or any other exchange unless I'm actively trading.
+1 on NQT
+123 on the bold text. This is good practice and this will prevent a lot of headaches for newbs/amateurs. Never have funds/coins out of your hands unless actively needing to trade/move/purchase/sell etc.
I agree with this sentiment completely. Never leave anything that you're not willing to lose on an exchange.
However, I will note that Cryptsy has a nice auto-sell feature. As soon as coins are transferred into your Cryptsy deposit address, they are traded out for BTC, and the BTC is held. Assuming that your NMC amounts are small (as they are for most individual miners), you may feel comfortable leaving those BTC in Cryptsy for a day or two at a time. I have found it helpful to auto-xfer my NMC to Cryptsy and use it to invest/trade small amounts (like .01 BTC) in other altcoins that catch my interest. Of course, I generally withdraw those altcoins ASAP to a wallet under my control. Not that they are worth much, but it is fun to dip your hand into many pools and to get a sense of the flavor of the various altcoins. E.g. I found it interesting to reserve a name with Namecoin, and to set up Proof of Stake with Peercoin.
