Ripple is a unique coin. I don't even consider it a cryptocurrency, to be honest. In a sense, its a payment network that's meant to facilitate and strengthen the "relationship" between our traditional fiat currencies and the new cryptocurrencies. Because of this, I can't necessarily consider it a cryptocurrency because it doesn't succumb to some of the primary principles that make cryptocurrencies what they are (such as decentralization, proof of work/stake, etc.). It would be far more appropriate to deem Ripple a payment network that utilizes the blockchain.

That all being said, Ripple can somewhat appeal to two huge pools of investors -- those who want to invest in cryptocurrencies but are too "risk-averse", or think they serve no purpose, and those who, simply, want to invest in cryptocurrency. Because Ripple intends to get as many banks on board, more traditional, conservative investors will see value in this coin. And, because Ripple markets itself as a cryptocurrency, "riskier" investors, and all those who believe in blockchain technology will see value in this coin, as well.

So, though I don't necessarily agree that Ripple is a cryptocurrency, I see a ton of potential with this coin (which is why I purchased it for 0.02 cents back in 2017).
