oh thank you , But I do not know why you need to know the price in 2019. can be tell me the price 2026/27 
I think you didn't catch the sarcasm there dude. If you can't predict the price of btc in 2019, how on earth can anyone give you a decent figure for 8 or 9 years from now? Bitcoin may even be obsolete by then, who knows. Or mr. Mcafee may still have his dong and 1btc is worth more than 1million.
