A stable coin needs huge financial backed up, popularity and acceptance in the cryptoworld even in the few countries. Development is not very vital here. You can find more then 3000 coins are already in the market but stable coins are only handful turn.
That's right, and if the developer doesn't have enough power it will be difficult to reach the target. The most difficult thing is to form a market capacity that is much influenced by investor confidence and a wide network. Most people are also more interested in unstable coins or tokens to maximize the chance of volality.
