the blockchain is most talked and underdeveloping technology in the world in all areas so this market slow down is good in one aspect many will participate in the form of buying bitcoins
I also think that there is a connection with the declaration of Trump about the trade wars. And it's currently starting to give itself a good buzz as the price goes up again.
I hope the market will recover and all coins will grow again and the previous prices will return.
As you can see the market is recovering right now but it's impossible to say that "ALL" coins will grow again. There are few coins that has to went through red when majority and bitcoin is on green.
But many investors were scared off by what is happening in the market.
Let them be scared, this is how investment works. If you're not willing to take the risk, don't invest.
