I made my first post on 29 Sep 2021 and it was an introductory post about my Splinterlands journey. Since then, it has been around 3 years and I have been actively posting and curating on Hive.
your HP growth is nice. I have been here since 2017 december but I am not sure if I will reach 10k HP by the end of year. So you may get similar results sooner. Good luck.
