see this will never happen. there's no way the ethereum price is at $ 40. ethereum is supported by a large community so it is difficult to make this coin destroyed. the only ethereum problem is that too many ICO projects use their platform.
I put my bet on it, just hopefully we will never see eth price at $40 although nothing is impossible with the cryptocoin. Unfortunately, ethereum, who has such a big supporter, suffered bad luck this year. So, it seems to me a little annoying if rely on such thing.
