The name is also stable coins, if the others show red color when the weak condition of the coint does not have a big effect on market pressure. It means that investors are more comfortable investing their investment in conditions that are affordable. A safe choice in my opinion.
For payment system, stable coin is really better since it's not volatile, no everyone who transact online can take the risk of volatility so we are seeing this happens. Actually I am happy with this kind of development because these stable coins are still just part of the crypto market, when they get popular and grow, the effect would result on the entire market.
in addition, we have Libra coming, not sure when but they are a big thing in the market.
