One month of playing without investing : how much I made ?

Today marks exactly 30 days since I started Splinterlands.
I only bought the spellbook at the start of the game, and I wondered how much I made just by playing the game and without investing any other dollar into the game.

Here are the results that peakmonsters display for me :

I must add I didn't try hard : only went to Silver III two or three days, and did not pack some gold foil card nor legendary.

I must say I'm quite pleased with my results as the value of the cards is not the only way I can make money on splinterlands. I also got 5 SPS thanks to airdrop, which is an additionnal 15% gains, and I also made some dollars writing here on splinterlands. I didn't took into account the current value of my dec, which should add another 20%

Overall, the experience so far is excellent. I can't wait to play 11 additionnal months and watch if my profits will go up exponentially.

What about you ? How much did you made ?
