I believe in bitcoin. It is traditional usd in cryptocurrency and it will be used for a very long time.
You have a beautiful chance to buy more.
For me,now people are too much used to with this kind of ups and down. Rather than panicking lots of people look for this kind of opportunity to buy some bitcoins. I think that some of the major investors just brought their bitcoins to Fiat. This is a short period in which the market will play a little their positions. Soon to be rise cost up and will be patient.
