Ripple is more efficient than Bitcoin, it only takes a few seconds to transfer your Ripple and complete the transaction, before you get bored when you are using Bitcoin.
You need to understand why this is. Paypal and VISA are faster than Bitcoin in a way due to the underlying mechanisms. I believe Ripple has some type of trust based system where the nodes agree on who to trust. Bitcoin is fundamentally solving a different problem. Many people in the community are interested in Bitcoin because of the trustless nature of the network more so than the transaction speeds.
Also this shows you're very much unfamiliar with the speed at which Bitcoin operates. It's likely point of sale nodes will have code that checks the network for double spend attempts when accepting a transaction. Thus this means that 0 confirmation transactions are indeed likely to become the norm. Do you know how fast a 0 confirm is? It's very fast.
Ripple is more valuable in the future. In the near future Ripple will be the most popular digital currency around the world.
And where is your argument? All I see is immature naive wishful thinking. Nothing of substance at all.
since the price of it will be smooth rather than the Bitcoin. so, I prefer ripple more than bitcoin.
Market forces dictate the price, and Ripple has already had a rollercoaster of its own, thus negating your point entirely.
