Its just the beginning, UST from terra Luna will beat these two stable coins but all the same they are centralised stable coins, I believe in DAI which is decentralized more than others but I just don't know why it's not getting good attention
It's not that DAI doesn't get attention but because it doesn't have as many pairs with other coins that DAI seems invisible, but for USDT there are already so many pairs of coins available on all exchanges that USDT is more visible than other stablecoins.
