Not sure about the question. There's a big difference between real-life usage and day-to-day payment. A lot of coins aren't supposed to be day-to-day payment - XRP for example is 3rd in marketcap (yes, I'm ignoring BCH
), but the purpose of XRP is international transfers; it may be quick and low-cost, but its primary purpose isn't for buying stuff over the counter in a local shop.
For day-to-day payment though, obviously bitcoin. But more will inevitably follow.
