Ripple has been gone thru many challenges already throughout the years because of their main goal. What is happening right now to them is just one of it.

I'm not a Ripple holder but as I see it, I know that they will survive with what they are facing right now although I expect that more and more lawsuits or cases like this will be faced by them in the future. As long as there are supporters of the coin, the coin will survive and Ripple has a very huge community so I don't think that it will die just like that unless they will follow the footsteps of Bitconnect in some ways .
