Coins are a currency for purchasing stickers, themes, and emoji. You need to purchase Coins before you can use them to buy anything.
The LINE Points program lets you earn Points for using various LINE services and making purchases with LINE Pay. These Points can also be used to purchase stickers, themes, and emoji.
Points are exchanged for Coins at a rate of one Coin for every two Points.
The exchange rate may differ depending on the country you're using LINE in. See this Help article
