So, I have small amount of cryptocurrency I bought and mined over the years and will HODL, but I am seeing news articles and advertisements about earning interest on my coins. And the returns are not bad--5 to 7% per year.

It seems BlockFi is the front runner. They seem to have partnerships with the major US crypto exchanges, e.g. Gemini and Coinbase (I am in the USA). I am also googling and trying to educate myself.

But, I have serious concerns about learning my crypto to 3rd parties. What happens if the institution that I loan to, for example BlockFi, goes brankrupt? I assume I will lose my crypto. Would it be safer to loan to an exchange and I don't run that risk?

What are your experiences so far with loaning your crypto?
What place do you loan to, or recommend loaning your crypto to?

I have 80x $100 Bitmain coupons that I would like to sell, or if possible trade for higher value coupons.

Coupons expire 2018-06-11 16:51:00.

Options:

1. Trade all 80x $100 coupon for a few coupons => $300
2. Sell $100 coupon for $15.

No Scammers please. That means you,  FriendlySignal / CryptoCoinInvestor / or whatever name you will change to.
