Ripple is also a cryptocurrency that can be very huge. Ripple connects banks in the world. Imagine how many cooperations they have with banks. Banks are the richest organizations in every country. If most popular banks use ripple, it really can go even up to $100 or more. Ripple is really useful.
But anyway, don't make facts confuse you. Ripple is also a cryptocurrency and it can go up and down. It even hit $0.23 in November 2017 and reached more than $3 in January 2018. No matter how useful the cryptocurrency is, we have big players who can pump or dump it. If you are a long term trader, feel free to buy it now. But if you are a short term trader, I don't advice you to do that. It's now about 8,000 satoshi and it can go down any moment. But it has also a big potential to come back to 22,000 satoshi or more in the end of this year.
