The current trend of Bitcoin is quite volatile. It increased by around 600% in 2017. Of course there is a chance to jump in that level in this year. Every time the price falls , right time to invest in knocks the door. I have another level of trust on this specific currency.
I do not think that the price has grown by such a large%. This level will be difficult to achieve. The price may go up, but probably not at the same pace as last year.
