At the end of 2017 the value of bitcoins reached at the highest position. No one expected such types of growth of bitcoins.  It was really unbelievable . It continued at the first two months of 2018. But after few month later and the mid of 2018 it started to decreasing instead of increasing. The recent time the price always ups and down.   I doubt it'll be a massive drop, the overall trend is upwards and it's likely to stay that way for the next couple of years. It is expected after few month later or at the last of 2018 the value of bitcoins will be high position again.
