I think Ripple will crash soon. BTC is pending a rally. The slow transactions are annoying. The fees are a little too high. However, with how much BTC most people are slinging around, it's not a big problem. The exchanges are still largely BTC based. Doing something like converting to ETH, transferring, converting back to BTC is more annoying than just transferring BTC in the first place.
There is rumor that coinbase will start trading it! With that kick I think BTC will have a big problem to hold it's market share!
