They added a much more reasonable risk explanation after the event happened. Click the link that the submission is. Look at the before and after pictures
Where do they specifically exclude the risk of depegging?
From their website :
"As Stablegains is not a traditional US bank, the funds are not secured by the FDIC. While we aim to make every effort to understand and mitigate everything that can possibly go wrong, there is still a non-zero risk you can lose your deposit. Our advice is to diversify and never invest all of your savings in a single place."
Of course they are selling themselves as pretty safe, and I'm sure they thought they were.
But as you mention, it's like the 10th stablecoin to drop, so it's not exactly a surprise that crypto is a risky investment in any case.
If you’re taking this from their Twitter thread after this whole situation happened, that is definitely not the same thing as an upfront risk factor when collecting investments from people.
