With this last quarter of 2018 i did not put my investment in ripple because i cannot convince myself to invest in ripple, i heard some of my friends that ripple has not a potential to increase the price of this last quarter of this year so probably in 2019 ripple is good for investment.
Ripple has its own capabilities and Ripple is unlike other Altcoin, Ripple is a centralized Cryptocurrency. Ripple can be a big competitor for Bitcoin but doesn't defeat Bitcoin, because it is different in its operations. maybe in the future Ripple's development will get better so that from now on investing might be the right choice.
