I think ripple will remain conquering the position and stay as number two top coin
Ethereum will continue to drop the value,though i am not a ripple fanatic but i can see the dominance from this altcoin for the next year of 2019
Bitcoin will stay number one.and will never be overthrown by any altcoin for the next 10 years
Ripple does have a very good potential. Ripple is a unique coin because it promotes good cooperation with the government. While Etherum is currently experiencing a decline, I don't agree because I think that the development of Etherum coins will increase in the future. Meanwhile, Bitcoin will continue to be a coin with a very good market share and will become a leader in the digital financial system.
