I think bitcoin will not get back to its $20k mark this year but rather lower than that amount. I just think this year would be bearish, in total opposite of last years market.
yes I agree with you if we look at the market charts at this time the fact that prices are declining from year to year when there is an increase some time ago and suddenly fall back so far.
About the popularity of Bitcoin in 2018 will increase more and more and in future it will follow the increase trend and the growth of Bitcoin will increase the same. With the passage of time Bitcoin will be more stronger as compared to its previous stages and events because with the passage of time if working is continue on a business then this business will go on increase trend.
