Rainbow coins are kind of a gimmick, imo. If you draw a duplicate 5* you get 2 coins. If you want to do enough gachas to get 150 dupes, you're probably able to get the 6* you want through some other means first. It's still a cool little bonus, but definitely not something I'll ever try to grind.
Rainbow coins are pretty useless
I just added all my dupes and if I got rainbow coins from when I first started playing which was over a year ago I'd have about 22 rainbow coins
If it was 100 coins I could understand that even if 50 dupes is still a lot
I'm guessing there is going to be daily deals/special gacha which give rainbow coins but 300 is way too high to care for

OK, has anyone figured out how to get the Aqua stones found now in the Forge? There's supposed to be part of the loot drops of a unique mission from what little I've found. But I'm not seeing a unique mission for them. I kinda want to give my cute little Grim Reaper Dahlia her scythe....
For those wondering, the 100 stamina mission for red/blue manyus is working fine.

Nutaku neglected to add the main source of rainbow medals: leader tickets. They should be bought with leader medals and have a 92.5% chance of giving a 5*/7.5% chance of 6*. If you get a 5*, you also get 30 rainbow medals.
I wouldn't hold my breath waiting for aqua shadow fragments to be added.
