It has been steem:bts. But I think it's better to hold on to the bts at the moment after the huge shift in balance. The steem:bts pair can be traded on the bitshares dex.
I'm not normally a trader, it has just been damn fun to increase the bts holding.
Nothing wrong with that. Sometimes sticking to what you know is best. Trying to trade projects that are outside your comfort zone is not wise. I have friends listening in almost all major Slack groups for Dev teams so that helps me make decisions.
