Don't worry ! it is normal going up/down after instant increase for Bitcoin. Wednesday, Bitcoin saw 11.500 $ line. And now it is going up/down around 10.000 $ . it is totally normal. Just check the movements of Bitcoin for last one year below. I am pretty sure, Bitcoin will reach 15.000 $ in February. And it will go up/down around 14.000 for awhile and later another increase will come. Start to save bitcoin for your future.
