Yes. I'm 100% sure BTC can pass again 20$k. But I think it will happen in 2020 or 2021. 2018 is the very very bad year to the crypto. The whole market is like a bearish market. However at this time it difficult to pass 20$k. But we can see some pump this year, but it not a strong pump. Finally, My opinion is, Bitcoin will rise up again and pass 20$k. So be patient and wait for the pass 20$k.
