I believe this is merely temporary. This is the result of people moving away from Bitcoins because either they cashed out of bitcoins or they are moving away due to the fact of the network problems with it. It's been the normal course of bitcoins and has been happening again and again in the past. So the best option is always to move to altcoins for now and when bitcoins does pump move out of altcoins and cash out the profits to bitcoins.
Of course, just what we have seen previously, market going down is only short term, I don't know about altcoins market though. And yeah I would agree with one member that it maybe due to coinmarketcap removing Ripple coming from South Korean trading platforms:

However, when the dust settles and understand what really going on, they will go back to the scene once more pushing the price all over again.
And then there the news coming from China, banning bitcoin mining farms. It's still not clear though, as we all know that there's a lot of contradicting news from the government as far as bitcoin and crypto. We will see how it pans out.
Rather than focusing on the negative aspect, I see this as the perfect opportunity to invest into bitcoin and some other altcoins, considering that their prices will increase in the next 2-3 weeks. Like what you said, the decrease on its price was due to the domino effect caused by bitcoin since almost all of their increase in prices are directly proportional to bitcoin's price.
Nevertheless, this would be the perfect opportunity to risk and to explore other altcoins like ripple due to its potential in the future. Lastly about China's banning of miners, this may be a double-edged sword in the price depending on the extent of damage done.
