2018 is another year for bitcoin as many people are still coming to get bitcoin as their investment and savings for the future.
As long as there is a new addition to the community the demand of crypto will continue to grow while the supply remains at a maximum number of 21,000,000 bitcoin. this will affect the market blow as always. 2018 will have the blow and bitcoin will overpass the 20,000 USD and will hit the new milestone of 60,000USD before the year ends.
useless predictions posts like this is what tricks new comers into thinking that Bitcoin has nowhere else to go but up. When in reality, Bitcoin faces issues internally(scaling) and externally (regulation,bans,etc). Nothing is certain until these issues are cleared up.
