But perhaps the price for bitcoins can go much more below due to the unclear statement from the south korea government about shutting all the major crypto exchanges. I think it is increasing the FUD which is making each market to go red. Hope it is stopped soon and the price starts rising again. for now, i would suggest to keep an watch on the graph and anytime you find the price is going up, just purchase the coins and hold them for good time to have a good profit. I am sure bitcoins will cross 40k$ in the upcoming year i.e 2019 which will indeed double or even multiply our money in good numbers.
