i would hate to see all the suicides from the crash of eth. spare yourself and get out now.
eth is nothing but a house of cards with other houses of cards built on top of it.
in other words, eth is a scam which enables other scams. it won't end well...
would be nice if you could give some more input that just saying "it's a house of cards", like the reason for example or why you believe it's not sustainable, it would help us to understand your position. From my side, I'll tell you why ETH is not what you're saying. It's survived for about two years now (quite a feat in the crypto world), it has a market capitalization of about thirty billion (which mean people trust it enough to put their money into it), it has a fantastic ecosystem of thousands of projects building on it (have a look at ICO's), the founder is both young and very skilled, the protocol is being enhanced very often and soon many new upgrades will make it even more attractive, such as PoS or the upcoming privacy features.
