I have given my active and posting keys out to sites (bots) that use them for good. But all my steem is in SP. I monitor those accounts weekly to see if anything is disappearing. If so, then out comes thei Owner Key and I change the other two. Risky, I know but never put more on line than you are able to lose. For me that figure is 200k in a single account. More than that and it would bother me to lose it.
