150 ETH OR 9.5 BTC?
Almost worth the same value now, but which one is better for holding untill DEC 2018?
If for the long term until the end of 2019 you better hold an eth coin. But if only for the short term until the end of 2018 choose bitcoin.
But I think your capital is quite a lot and I recommend for the long term not only until December 2018. Because with large and long-term capital you get more.
