At the end of this month, 20k will come in. The price of Bitcoin will certainly be a fast growth this year. Bitcoin price will definitely reach 40k. But getting 70k is a little bit harder.
There's no chance of 70k $ this year. It's possible around 20-25k $. The end of last year and the decline in prices gave people a little bit to think about. The price isn't growing so fast and people are hold bitcoin counting for growth.
"There's no chance"
There is always a chance, i've read and laughed upon various such claims throughout my time on this forums. "No way bitcoin can cross $2/3/5/10k in 2017". How can you lack imagination? ignore possibilities? I agree $70k is too high of a mark but its never impossible.
I guess you were just presenting your ideas on this, maybe this is what you believe and you aren't open to more possibilities.
I personally think bitcoin will cross $30k this year, because of VARIOUS reasons.
