I wonder how ripple will grow in 2018
If you talk about its price, it will not grow very much. However, it will stay a very stable altcoin, a very convenient stuff to deal with banks. Ripple must be kept in all our wallets s for sure!
I agree, ripple is belongs to the top Cryptocurrency due to it's market cap value but a single token priced very low, lower than a buck. But ripple has indeed a stable value unlike other Altcoins.
