I would be very happy if that's the max of the downside risk.
We have seen the bloom and bust of bitcoin twice previously. What amazed me about Ethereum is that it didn't encounter a sustained period of trough. If the minimum price of Ethereum in next five years is $200, I think we may get to $1,000 very soon, given the bitcoin previous cycle. That would really make me very happy. Just think of Casper, Raiden and all wonderful development are not yet released. We just need to wait for a year and we will see.
