Reading this belatedly and just only now recalling that I used to loan out quite heavily on Poloniex in early and mid 2017. Didn't know it at the time, but my BTC was snapped up at really big interest rates (if I recall some even almost 1% daily) because of the huge FOMO going on especially in the alt markets.
Good times. I remember getting 1% daily as well for a short while.

Yes, I was there too. Nowadays, I've lost 16% and it will take me many months to get them back. On other platforms, of course...
Nobody has talked about it, but one thing is strange:
Clam's crypto-crash was on May the 26th, but Poloniex took money from its customers on June the 6th. For 10 days, they had covered the loss. And I didn't even knew that the Clam crypto-crap had crashed. Then, suddenly, Poloniex changed its mind, and decided to make their customers pay.
