Tip #10 - Learn to Post on Splintertalk.io
Tip #12 - Participate in Splinterlands Contests
Both are underrated advices and really can help you gain a lot, even more than the game itself if done properly, in addition to posting, I do come across a lot of posts (like this one) filled with valuable informations that broadens my knowledge about Splinterlands and Hive ecosystem in general.
