Dash's solution works, but is not preferred by the general crypto community at this time.
Rules for Radicals: Never go outside of your own peoples' knowledge.
DASH forces people outside of the realm of common knowledge. This has always been the case... this is why DASH has always had an uphill battle, and frankly, I'm fine with that. Resources should be spent on development, not trying to educate stupid people.
The problem with privatesend is that most people know what cryptography is, but they have no clue what steganography is. They've never even heard of it.
They go along with the thing they've heard of. They consider it "best" because they have no clue what they're comparing against. They have no understanding of the alternative. They don't even know what it's called. They fear the unknown.
Which is better?
A Ford Mustang?
or
A Smarglack Sorgenfloob?
For all you know, a Smarglack Sorgenfloob is a spaceship. Which is obviously waayyy better than a Ford Mustang. But, you don't know that. You've never even heard of it before... So you confine yourself to the realm of what you know, and buy a Ford Mustang and declare it the best because you wouldn't declare the decision you just made to be the worst, your fragile crypto-snowflake ego depends on being right about everything always and knowing everything. If you admitted that you didn't know everything, that introduces the possibility of being wrong, and that just won't do! Ask pretty much any cryptotard...
An introduction to the concept of hiding in plain view; steganography, would not go amiss. Audit-able privacy is best privacy. I don't know of anyone who has even attempted an infographic or simple video about this.
I describe it to people as putting all your money into a cash register with everyone else's money. You get back the same number of $100s, $50s, $20s, $5s and $1s that you put it, but there is no longer any way to know which one came from who, or that you have them, until you stick your name on a TX. So, don't do that.
Cryptography is essentially a ticking time bomb. It's not a matter of if the whole thing will be unmasked, but when.
Since DASH's steganographic version is optional, transparent, and not dependent upon computing power; I say that's better. DASH doesn't hide the connection, it eliminates the connection. Whether or not the DASH you're holding was once used in a drug deal, or to pay a hitman, is not your responsibility, nor should anyone be able to check and see, or falsely accuse you of criminal involvement by means of a connection you had nothing to with with. No amount of computing power can counter that. the guilty-until-proven-innocent realm of "regulation" doesn't like it, but that's kinda the point...
"Regulation" is nothing more than a nameless, evidence-less criminal accusation from which you are forced to prove your innocence.
But, making a large effort to corral the ignorant and force them to learn is a waste of time. You can't force a herd of cats to sit down, hold still, and learn the math you're trying to teach them for their own good. It'll never happen. As with everything else about DASH throughout it's lifetime, DASH makes such leaps that it takes a while for the derps to catch on. Just keep doing what you're doing and the weak will have regrets for not keeping up. Nothing you can do about that without slowing yourself down. It's nature.
