I see no reason why should we choose just one of them at the moment. I think they both will perform very well this year and will reach new highs. On me i prefer with ethereum. Nowadays ethereum has many investors and supporters who supports them. I bet on ETX, because it has not yet collected its value, of course both currencies will go up, but the ETX has more potential. For me both of them are important for me .. and we dont know if what coin this year will getting higher.
I prefer to invest into both if you have the ability and capital enough money. Why ? Because I think the price of Bitcoin will continue to grow and the price of Ethereum will also grow. Currently Bitcoin fee is very much therefore it is very important for us to look at other opportunities and take advantage of Ethereum while still able and there is still a chance. Ethereum has a great development and I'm sure Ethereum will follow Bitcoin's trail in the future. I wish I could collect Bitcoin and Ethereum as much as possible to bring in a lot of profit to change my future, boost my economy and keep my family.
