Also, not all stable coins here have real backing of their respective fiat currency. So you need to be very careful about these stable coins, as they may fall down anytime when the team behind it decide to stop their development or one of the team members decided to run away with large amount of coins and sell it to the market.
If there is a real backed up by their own currency fiat then everyone will be fond of using that. Even the famous usdt are not acknowledge by the US. This is own by a private company so the risk here is the same with other tokens and everyone knows that even they hold their stablecoin they will not see it grow as its description truly for that purpose. They will not be called stablecoin if they move too fast.
