People generally invest in Ripple (XRP) for four reasons:
1. It was one of the first altcoins. Ripple even existed before Bitcoin as a network of trust lines, a digital form of hawala banking. So it was based on trust, exactly the factor that cryptocurrencies try to avoid. Not a good fit.
2. One XRP is much cheaper than one Bitcoin. People forget that there are 17 million BTC but 99 billion XRP, most of which are owned by Ripple, the company that created XRP (and which lies about having done that, because it was an illegal way to fund a company).
3. A few banks are experimenting with Ripple. But it's unlikely that they will actually use XRP.
4. Paying with XRP is very fast. This is the only good reason. But Steem has the same advantage, without even focusing on payments.
