Bitcoin prices are dropping too much...
this is natural in crypto market.Check history of crypto market
Is there a possibility of a rise in the future?
yes why not.after dump,bitcoin pump.Of course it will happen
If you say yes, when will the trend turn around?
Need more support to start pumping.Hope it will happen soon.But no one can tell you the exact date.
And how much will Bitcoin prices go up on end of this year?
No one can tell you the exact price.Only traders can predict the price.This is not new question.Maybe after this dump bitcoin can hit 8k$ end of this year.this is my personal opinion.
