Why would I want to keep BTC in my investment portfolio? That's most hyped and quite overvalued coin I'd say.
There are other more technologically advanced coins. Is it because of "digital gold" and store of value properties?
BTC will grow further despite some times it failed. But most of the altcoins will rise too. People believe in Bitcoin they will put more and more money in it I am sure. Dont be worried about Bitcoin.
The price may dump a little deeper but I still believe on its great technology. And people should notice this, don't just be affected by any news make your own study about bitcoin. I am holding bitcoin for good until it makes me rich.
