Here is what is going to happen: the founders of that company will dump their billions, and let the vast majority of investors holding their bags. It will be like BitConnect, but 10x the proportion.
I'm not saying it will happen in the next month, or year, but at some point it will.
I do not know about that, there are people that oppose ripple due to its nature and its relationship to banks and other similar entities, but BitConnect was clearly a scam and many established members in the forum warned people to not invest on the project and yet many people did and now they are paying the consequences, so I doubt the same is going to happen to Ripple.
