yes, I think bitcion will be more stable in 2018, the matter of being a means of payment is not fully and fully realized, only certain countries that accept and legalize bitcoin, I think with this very fast technological developments in a short time bitcoin will be able to be the best . I am sure that every government institution up to now in every country continues to review and evaluate bitcoin to serve its people who have already joined bitcoin, so that a short time bitcoin will equally become a means of payment in various countries legally. let alone now in the global economic market.
