I'm not sure about altcoins and tokens -- that's a whole other mess. But regarding Bitcoin, I think last night's lows will be it for a while (maybe another retest of the bottom is in order, though). It doesn't seem like this news has all that much bearing on BTC. There was some FUD about the PBOC banning BTCCNY exchange, but I think that's been cleared up and is not the case.
There could be an argument made that money coming into ICOs via BTC were pumping up the whole market, and now that the reverse might occur, that the BTC market could deflate. But it's not even the case anymore (even in Chinese markets) that BTC is required to access ICOs; ETH/fiat markets are very liquid at this point. So I don't think it's a major factor.
