I do not think it could increase by 300% until the end of the year as the demand for Cryptocurrency is decreasing and all investors are feeling depressed in this market because they are constantly losing money in time recently . I personally choose the right time to invest because by 2018 only investors lose money and very few people can make a good profit.
I wonder how it would be at the end of this year for cryptocurrency. I agree that this time, many investors seem to weaken their trust for crypto, I'm not sure sure the demand will end up high. But no one truly knows about this. Let's just wait until the time comes.
