Also It's good to hear that they are not going to expire or something I guess, but at this rate how long its gonna take to collect 300?

The key to getting a rainbow coin is to repeat

Now that you mention it, yeah I just remembered that I got it with my repeated Anemone (Miko). And yes I know about the current gacha but its too expensive for me right now, I'll wait for a better offer.

Thank you for your answers guys you are really helpful.

I know this is very late, but here...

Haha, thanks man. Yeah I already have my skillblooms. Out of curiosity I was going to ask about the guy in your screenshot but just noted that is from discord. One more reason to join fkg discord channel I guess.

Just know that it is going to reset on the Tuesday or Thursday after the date listed. If they did it on the 30th, which was when we had the Thursday maintenance for that week, people would have been like... "Oh no! I forgot to do the exchange! Woe is me! I have 4 Life crystals but I could have easily farmed 1,000 today but the developers went ahead and reset the shop on me! Disregard the fact that even if I had the extra four days I would have forgotten to do it anyway! They reset the shop early and now my entire life is ruined.... *dies from sadness*..."

Just keep working at it until you can fully knock out the shop the day it resets so you don't have to worrying about it, and if you happen to forget after the maintenance, you have a full month to force yourself to do it. I did mine about one minute after the maintenance ended on Tuesday (after I did a quick garden capture and gather since those are usually waiting on me).
