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.
Bitcoin is already tested by time and that make bitcoin last long. Don't make this as a reference for the future of bitcoin because bitcoin now is one of the most circulated currency in the world.
