I think the BTC price action this year will be more akin to 2013 than 2017. We're already seeing a major surge early in the year which I think will continue over the next 4-6 weeks. This will be followed by a volatile correction lasting several months (30-40% downside expected). Uptrend will then continue in the summer towards the 200-280k range before another larger correction down. Just my opinion, not financial advice.
