USDD APY dropping from 30% to 10%
You can easily earn by with soft staking via Poloniex.
But as we know, from painful lessons, high yields from a stablecoin is not sustainable.
Poloniex has recently announced the yield will be coming down, and it takes effect on Oct 20.
Though as of writing, the APY is still displayed wrongly on the website and app. Do note it is now only 10%. Much lower, but still the highest for a stablecoin.
If I were to bet, it will go down further in the future.
