I think yes. There is no reason why it shouldn't grow next year. The news are all positive, mostly all exchanges are bought by traditional banks. So huge investors are ready to enter the market.
Just like what you said about bitcoin, but according to the signs may be quite a long time, and as I see it may be between 2019, and will increase continuously until the end of the year. But I still want to say, I assert that bitcoin will increase in price in 2019 after heavy discounts.
I'm not sure the price Bitcoin will increase in 2019 later, but I believe that in the next year, 2020 or 2021 it will happen. I see the price movement of Bitcoin is still stagnant, not much changes. So in my opinion the price Bitcoin will remain as the current price until 2019.
