The coins are basically substitutes for your rolls in-game or in web events like web gacha.
The Coin per Roll ratio usually is 1 for 1200 - 1600 point gachas in game, 6 is for 7500 point gachas and 12 for 12000 - 14800 point gachas.
Web gacha is 2 coins per roll, and the minimum amount of coins to play the web gacha is 10 coins.
