Transaction times eh? You see a lot of complaints by the users do you?
...
Because there are almost no users. According to Bitcoin wiki, Visa alone "handles on average around 2,000 transactions per second (tps)" (https://en.bitcoin.it/wiki/Scalability)
Average doesn't mean maximum.
Visa is capable of handling 30,000 tps.
Thirty thousand transactions per second.
Bitcoin can only handle seven transactions per second. Not seven thousand, just seven (7).
Good luck, new world currency
Comparing a nascent payment network with the largest payment gateway provider in the world is a great comparison!
