Back in June this same scenario happened. Take a look back at the grand gesture known as bleeding red:

At the time Bitcoin was down 6% after being down double-digits at one point and most other crypto in the top 10 was also seeing some nasty falls. It happens from time to time as we all know the volotality in the game of this type of market. "Bear" in mind (yes pun intended) that Bitcoin was at $2700 range and that was less than 3 months ago and currently sitting around $4400 at the time of this post. Hell, Litecoin was sitting below $30 then and now over $70!
It seems when something even as insignificant, at least in my eyes, happens, such as Coinbase experiencing an outtage, that crypto as a whole takes a nose dive. Everyone needs to chill and realise the problems are temporary, that this type of ecosystem depends on computers, technology and code to run. If something glitches, it will inevitably go down, no doubt it. But that doesn't mean that everyone needs to panic and do a sell off.
I have stated before that selling off only makes it easier for those who hold to buy up the sold off items on the cheap and those that sold will have to work twice as hard to get the balance back up to where they were previously. In my opinion, unless the almighty Bitcoin takes a tumble down to a grand, I'm not panicking any time soon...and neither should you...HODL peeps!
