Bitcoin and 2018, will skyrocket, although after a meteorite can become bubbles that may break at any time but bitcoin investment remains a trend and will not hurt.
Bitcoin is going to be very high at the end of 2018, people are now investing which is making market too high, I think almost 3 or 4 year holding will give everyone high profit, buy now and hold I am sure your price of bitcoin will be more than double so buy now and dont forget to sell when it will be high at the end of 2018, same as 2017 price will rise too high at the end of 2018.
