LeoFinance: So far I'm not that acitve on LeoFinance, but I published one blog yet in the LeoFianance community, so I would say my strategy here is blogging.
Splinterlands: I just play and buy cards if I'm able to do it. Maybe one day they rise in prize and maybe I' sell some cards on this day. But rigth now playing Splinterlands makes fun and I'm not that interested in taking profits.
