Didn't know ripple was created in 2004, make sense that the market cap is bigger then but why has this crypto not taken off in 11 years?it enables secure, instant and nearly free global financial transactions of any size with no chargebacks , that's already pretty revolutionnary isn't it? and that's the main reasons average joe will use crypto other than traditional method.
Does it means ripple doesn't even use the blockchain? why is it even called cryptocurrencies ? is it source code open?

thanks
