If you have 10000$. It's better to buy ethereum. 2018 is the year of ethereum 
Buying bitcoin next year wont give you alot of profit. It might increase in value but not twice its base.
Best of luck

Actually, there is no such information that next year is for ethereum. In fact, the reason why we're here is just to promote the entire cryptocurrency not just only bitcoin or ethereum. I think you're just hoping that ethereum will go further by next year as bitcoin do so.
