Don't know why but that amount of transactions still seems very low compared to credit card transactions... there is still a lot of space to grow...
The problem is, transaction fees are already so high that it's hard to justify using Bitcoin to purchase a cup of coffee, and Bitcoin processes 1000 times less transactions than fiat payment systems. And Ethereum or any other altcoin are in the same situation, so actually there's not much place for growth and adoption untill cryptocurrency protocols get major updates that will significantly improve their efficiency.
Ive introduced a few members of my family and friends to bitcoin but more and more recently ive stopped using bitcoin as my entry token simply because by the time i buy it off coinbase for instance and then send it to them the amount they initially invested has been lowered. Hopefully this problem will be a thing of the past and i can stop buying altcoins for this purpose.
