I was a bit confused when I saw the total TX number for the last 24 hours on blockchain earlier which was around 300k and that does seem extremely low. Perhaps it's the middle of the weekend and that's why.
Never really thought about this thing.......... How will we be able to use Bitcoin if there will be like 50 million Bitcoin users? It'd be a shame if Bitcoin won't be able to sustain so many peoples' transactions.... It's growing fast!! Hope we will be able to use it just like we are right now!
