Regarding steemit I still do not know what is a safe way for most of us to store are keys. Every time I make a transaction I always need it on hand. I do at least one transaction a day. Curious what ways to protect a steemit key?

I currently have it stored on a usb drive but not encrypted. I have heard about spyware and key loggers so have up to date security software on the computer. Still the fact that the key is used daily makes me feel vulnerable.
