If I'll be investing on it, I'll wait until they are done with everything. The risk of volatility and then the risk of being delisted is everywhere is not a good combination of risk that you might take. I'll take a look into another coin that's better than this coin. And it's expected that most of the exchanges would avoid this with the fresh lawsuit that it just had. It's either they delist it only for their US residents and keeps on being traded for their other offshore traders or completely delist it to avoid any relevance to the issue.
It will never be done with everything though,,, XRP is just going to be an endless problem from the beginning already you could see trouble was spelled all over the place. Lawsuits are more common for Ripple than good news, this is not going to be the last one unfortunately. Hold what you have, I do the same. But would not get in more.
There will be an end on it and it could be a good ending favoring XRP or it won't be and favoring SEC as the winner. There will be more but for different projects and altcoins if SEC keeps on working to track down those projects that have violated their terms.
I'm holding what I have right now and I won't be investing on XRP, it's risky to me to have it and won't be having my share on it. It's just an explanation that "if" I'll be getting it as an investment during their hard times.
