What do you say about Ripple? Should I invest?
You should not, as a centralized currency and that's not so good as a crypto. Ripple team is only focusing on the how many profit they can get from their business. This is a banker platform. I won't meantion any evidence but you can try to read all of the news related to the ripple. Try to invest in another just lik ethereum will much better.
I see many people who're into Ripple are also into other traditional stocks investments. So this maybe is the reason. Ripple is most likely to be similar to traditional stocks. Maybe ripple is really centralized.
