There are few stablecoins that is available in the market and I don't think that we need another one but if the stablecoin you were creating has some useful and unique features then the crypto community might give you their full support but never forget that you must have a financial backup for your stablecoin and also established lots of partnership with different merchants so your coin will be more useful for paying goods and services.
For sure partnerships are one important facet of bus dev.
There's are about 140 stable coins in total that have either been launched or are being developed currently. I think that the crypto community is just one component of the total market for an anti-volatile crypto-asset that isn't centralized and that can scale comfortably to a marketcap of trillions.
Saying that, the crypto community is the most important segment of the market, because we are the early adopters that dictate the trajectory that adoption will take to begin with.
