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.
I agree to you this year is a challenge for all the bitcoin users. If they are weak they will leave and for those who believes and trusts bitcoin will stay. We must decide if we want to stay or leave but for me I stay and continue in investing in bitcoin.
