If you bought 1000 ether at $2, you'd be out $2000. If it is a glitch and the price does recover, you've made about $340,000. (Sounds like a scenario out of a post from the sub-reddit /r/LateStageCapitalism, doesn't it!)

Of course if you do this on every exchange, you multiply your risk by the number of exchanges, and your reward probably only comes out of a single one of those exchanges, unless it is the real deal "flash-crash" coin-wide permanent glitch-out end-of-the-world everything's hosed and the price is never coming back, in which case you lost $2000·N which sounds a little worse.
