my brother invested almost 2500$ but he is still holding  he is also the same as you, because bitcoin is volatile he lost almost 60 percent to 70 percent of his investment. but also he didnt sell he is just holding bitcoin. because he is considering bitcoin is a long term investment, i recommed him to do some campaigns like facebook, twitter, medium, signature etc., so that he will get back the value of his orignal investment and earn more. actually this is also a great opportunity for everyone to buy while the value is cheap and sell when it is high.
