Cryptocurrencies suddenly in red

Dear Steemers,

I'm wondering why cryptocurrencies are suddenly turning red fast, especially the altcoins. Is the market that sensitive to respond on a tiny bit of news?

The only thing I can find is this:

Bitcoin can be an asset but not a currency, says China Adviser - CNBC

Something to worry about? I don't think so. This seems to me a quite conservative way of thinking. Or am I wrong?

What do you think? And what will happen next weeks?
