Already the biggest volumes are with direct pairs with USD. Any deviation from actual FIAT is in my opinion a good move. Pegged currencies of course aren't a great improvement but at least they are not a direct endorsement of the bank system. Some of them are even more centralized and trust based too! But that's why it's good to have currency competition.
The more stable-coins there are, the more competition there will be for better products, and the more pressure on banks to be more accepting of crypto or lose deposits to their competitors.
Agree. The more stablecoins on the market, the greater the competition will be. I'd imagine that renowned banks will launch stablecoins of their own for the whole world to use. COVID-19 has just increased the popularity of crypto/Blockchain tech, so I wouldn't be surprised to see more stablecoin offerings in the future. As far as centralized stablecoins go, I would think twice before putting all my hard-earned money on them. Apparently, stablecoins like USDC and USDT are too centralized to the point where the stablecoin issuer can freeze your assets on the Blockchain. Centre has already done this a while ago (link to article), while Tether has followed suit (link to article). It shows us that most centralized stablecoins are subject to a single point of failure, effectively bringing traditional banking to the Blockchain (Banking 2.0).
Considering that centralized stablecoins are too vulnerable towards manipulation, I'd say that decentralized ones could take the world by storm in the future. As far as I know, there's only one decentralized stablecoin backed by decentralized crypto assets. And that one's called "DAI". The market may be saturated with centralized stablecoins, but it's in need for more decentralized options. Believe me, once people face the same situations as traditional banks by using a centralized stablecoin, they'll leave the game. Blockchain tech is all about decentralization than anything else. While at some point regulation is necessary for the industry to thrive, sometimes it's taken too far than usual. Time will tell us whenever stablecoins have been a failed idea or all the other way around. Just my thoughts
