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.
At the beginning of the year until now Bitcoin continued to decline, and made some of its investors leave, many factors influenced people to leave Bitcoin such as weak beliefs due to FUDS news or they sell Bitcoin to switch to ICO projects with the aim of getting fast profits, you are right strong will survive and the weak will leave, before people buy Bitcoin, people should consider everything including enough savings to wait for a good return from buying Bitcoin.
