I've created a non-trivial amount of HERO via borrowing on the DEX, it is an interesting experience.

Here is how this contest can make people very wealthy:

1. Buy BTS

2. Borrow HERO using BTS as collateral

3. Sell HERO for BTS at today's price

4. Wait for BTS to go up in value due to HERO contest

5. Buy HERO back for less than you sold it for

6. Return borrowed HERO to the DEX

My question is: what happens when the contest ends and everyone cashes out by returning their borrowed HERO?
