In my opinion, some values make stable coins as important as a bridge between two economies - traditional (centralized) & crypto (decentralized):
+ the stable coin value is exactly equal to the price of a common fiat type by Proof-of-reserve. This makes new users more secure when approaching crypto, anyway they still find USD more familiar than BTC

+ stable coin is where traders/holders protect their assets during high volatility, simply because in their minds, fiat is still a measure of asset value.
+ stable coin becomes the first viable option to apply cryptocurrencies to the current economy without conflict with the power of state banks.
+ stable coin has a great impact on the price of cryptocurrencies thanks to the additional issue. BTC always increases when USDT is issued more
