Stablecoins needs to be backed by equal amount of fiat as collateral and audited by independent auditor. i.e. you need a huge capital to start with. It's not like the crypto project you could start with a 2 members team. The primary focus of stablecoins is the adoption and trust. A starting stablecoin should have a partnership with at least a good exchange or a few.
Yes Stablecoin must be strong from the support of fiat or gold and others, after that it is audited for the truth and the choice of the developers, and I think trying to develop a stable coin is not easy. There are several processes that must be passed for many to believe in the community.
