It's a risk in my opinion to hold bitcoin as this price , only if you are a trader or a speculative guy. Instead keep your cash to rebuy or if you want to enter now is a good price for a quick profit. Also you can use your bitcoin on a few good ICOS , like GIZER.
Risk is every where, risk were there when people even bought BTC for $600, but now you see what it turned to.
I personally do use my Bitcoins, because beside an asset I consider itself a valuable currency and transaction medium. Helped me to send money easily across borders for products and online services.
For me, though it is a risk to hold bitcoin for a long time since the price is not stable, I will still continue to hold it no matter what. I will not use bitcoin for buying things because I have a big plan where should I use my bitcoin. I am already planning which kind of things I should use my bitcoin in the future. So for now, I'm just saving my bitcoin and this year, I will not use any amount of it.
