“Given the dramatic increase in uses for bitcoin and associated volume through payment processors, it shouldn’t be surprising to hear that the number of daily bitcoin transactions has grown dramatically as well. The number of daily bitcoin transactions is on an exponential trajectory. At an average of approximately 55,000 per day, that figure is roughly double the rate in April and five times the rate at the beginning of the year. While much of this is surely due to exchange accounts being funded and withdrawn for speculative purposes, the quantitative data above indicates a significant portion is likely also due to bitcoin’s increasing use as a transactional currency.”
