For me its just normal to be worried as far as the price of crypto market is concern. Fortunately, if you do your research, every year in the month of January, the market seems to be bearish. Although I haven't noticed it until I do my own homework. Normal to be worried but you have to face that fact that the market can't go on parabolic, there will be down ward trend. The thing is not to panic sell and just be patience.
i am not worried at all about the market drop. if we see past charts (2015,2016,2017) they all looks pretty much the same. It is normal for price to go up and down, and so far, it is still up 1000% from last year, soooo...
This is what I'm saying. The past years shows us that at the start of every year, the market is always down. Lots of factors, but I wouldn't discuss it further. Long term we may see bitcoin touching $50K before the end of the year.
