Is it safe to invest in the XRP or we have to still wait for the stability of the XRP?
Don't buy as long as the situation not safe to put your money there! It isn't a wise decision to buy XRP if the XRP team still cannot fix the problem against SEC. I think you should know the answer yourself, mate. By the way, what do you mean "the stability of the XRP"? Do you mean "XRP price"? Mate, XRP isn't a stable coin. The price will always fluctuate and be unstable. Something that you must wait for is for good news from the XRP team related to the lawsuit case.
