Ripple and it's partner Stellar have gone mainstream in short order and hard to believe. In 5 days, I've doubled my money in Ripple and tripled in Stellar. In my opinion FWIW and judging by reading the various news outlets and from information I've received, Coinbase is currently integrating Ripple behind the scenes. Coinsquare in Canada has publicly stated Ripple is in the works as well as a few others. IMHO, when Ripple goes mainstream on Coinbase, the sky is the limit. In a week, it's surpassed many of it's competitors and total market share is over half of Bitcoin. It'll never remotely get close to what the price of Bitcoin is due to the supply but it's possible in my opinion to reach $50 by end of 2018.
