Well.. It's technically relevant.
Lets say we scale to 100x our current transaction traffic (And we better hope we do). How long will it take to fill up a 32G SD card with the blockchain.
This reality will dictate the solutions to these problems... it's relevant, But not insurmountable IMHO.
All true, but 32 GB sd cards are pretty low end at this point. There are 512 GB sd cards already (expensive, for now).
Obviously there are other solutions too, besides just storing the whole blockchain, as you say.
And I think it's important that we cater to the lowest common denominator. And that may be indeed much higher than a 32G SD card, but even though we are technophiles (mostly) here now, we want to shoot for the broadest acceptance possible. Bitcoin is still a mystery to too many. And just disseminating why Monero is worthy is a challenge of it's own.
I have been more interested in DRK since the recent drama... and I did a renewed level of DD over it.
The fact there are SO MANY people who are willing to buy into a platform with SEVERE problems worries me. Because if people can't understand why DRK is bad, then how will they understand why Monero is good?
Just musing a little...
It doesnt matter much. Because those who really need to have privacy will use the one that gives them privacy. They wont even dare to use the one that have obvious problems.
