Seasonality might be a thing, but if we look at what happened after the 2013 bull run, 2014 was a year without anything other than a continuous lower high down trend, and this seems to apply to 2018 as well. The year isn't over, and there might be a short lasting bullish upwards movement, but I don't think it will be strong enough to break several previous local highs.
It's better to just accept that we'll enter 2019 well under the $10,000 level. Historically the first few months of each year have always been the worst, so I expect some serious down movement there as well. It might even be where we end up setting the 'ultimate' bottom, which would then follow according to the ultimate bottom of January 2015 where the price tanked well under $200 but quickly went up from there.
My advice; remain neutral and don't expect anything from the market this year.
