I will like to know the reason why after bitcoin reached the maximum value this month it has been decreasing on a daily basis just at the time i wanted to invest the uptrend just changed suddenly. is there any hope of further increasing as some has speculated that it will reach $5000 by the end of this year?
One cannot be optimistic as to whether bitcoin value will reach $5,000 before the end of this year. Although the recent decline or nosedive as you rightly put was as a result of China ban on bitcoin local exchange and ICO activities.
