People who want to earn points just by playing the game, if possible

Hello, nice to meet you. Yesterday, I tried posting a strategy log on the community for the first time for 'First Log' and the same game. It was my first time posting, and when I logged in today, I was a little moved to see that gems had been distributed. I was a bit surprised because I received more than I expected. Is there such a thing as beginner's luck??? (I was thinking it would be lucky to get around 100 gems, so it feels like I was unexpectedly betrayed in a good way.) I don't understand the mechanism and ratio by which they were distributed, but I thought I might try to post something once a day from now on.
