Bitcoin price movements are now said to be good price movements, despite losing around 70 percent of all time highs in January, still marking great growth compared to places in early 2017. What's more, the world's largest cryptocurrency greatly outperforms some of the leading traditional companies like Amazon.
Soon I think there will be a "huge bull signal" and that is where we will see the same or greater price spike at the end of 2018. So bitcoin has just entered a new phase and it's not too late to invest or just get benefit from short-term trading by buying it at a low price and selling it at a high price.
