This year the price of bitcoin has dropped for a long time, and don't know how long bitcoin will be like this. I think this is a year of challenge from bitcoin, those who are strong will stay here and the weak will leave, this will be an option to determine the future.
2018 is not over yet but not good too. Compare with august price, bitcoin price still higher thatn 2017. Positive news will coming in market and market will recovery again and early 2018 many false news about bitcoin and many peoples panic without doing research to find the truth
