Im guessing I just use my BTC address that bitcoin gave me.
Truecrpyt it and backup my wallet on flashdrive? gotta be safe here
thanks for the informative reply!
Your bitcoin client for your main wallet should be off 99% of the time. decrypt it, mount it, use it, then shut it all down and encrpyt it again. And make sure you have a backup copy of the truecrypt file.
as others have said, these exchanges are not banks. don't keep your entire btc fund in the hands of one of these exchanges. transfer it in, use it, pull most of it back out. most people wouldn't keep 1000s of dollars sitting in their paypal account and they're 100x more secure.
