I found out a lot of information about Ripple and I decide now whether it is worth investing in this cryptocurrency or not.
Ripple is more centralized due to all regulations they are compiling with. You can invest on Ripple and join the hype to make some quick profits. But do remember that the currency is "centralized" so it may not be able to compete with the current crypto currencies. You could also try investing on Stellar (XLM) which forked off from ripple protocol and is more decentralized.
