What were they thinking? 20% yield?
I never expected it to last long and had a clear date set in my calendar when I would cash out, but to me it sounded like their decision to pump VC money into rewards. Lots of companies do that, see PayPay in Japan which used to give you 20% cashback on EVERY PURCHASE you made, with every 10th purchase in the system getting a 100% caschback, just so they can grow faster than others. It was bonkers and burned so much money, but now they are the dominant payment app in Japan.
So for me, put money in, ride some of that 20% while VC money is still around, then bail.
I also regularly monitored the reserve dashboard how much reward money was left, the ongoing proposals, and how the APR was supposed to change month by month until it reaches a fully self-sustainable rate. In fact, when reserves for anchor dry out, it was supposed to automatically reduce the rate to the sustainable rate which was like 4-5% or something.
I also put money into UST on Binance to reduce my exposure to onchain Terra, because I trusted Binance more than I trusted the protocols.
Well, long-story-short, about a week before my cash-out date Terra collapsed and I lost 90% of my investment. That was a lot of money for me and it will take a long long time to re-save that.
