150 ETH OR 9.5 BTC?
Almost worth the same value now, but which one is better for holding untill DEC 2018?
75ETH and 4.75BTC, that is how I would do it or if you are in doubt go all in bitcoin.
I think Ethereum has much more potential for further growth than bitcoin. Ethereum is a younger coin that has a great practical applicability in the field of blockchain, so this will ensure the growth of the price of ETH.
Both have potential that is why picking both of them and splitting funds between them is smart call.
