You overestimate the negative sentiment the masses have on financial institutions and governments. Yes, everybody complains but most are content with what they have. It's certainly not so drastic that people will go through the incredibly difficult processes of setting up wallets, getting money into the system, buying BTC and then finding a way to spend them, which we know are far and few between.
Not to mention, Bitcoin is becoming a bad word associated with all things criminal much faster than it's becoming some "beacon of light" as it relates to currency. It's highly volatile, it's clunky, difficult and confusing and it's absolutely vulnerable to far too many variables. Image is everything and Bitcoin is losing that battle. It's attractive to diehards and high risk investors sure, but most of them have no clue what mainstream wants because they are completely out of the loop.
Bitcoin is like Napster. It has shown us the way but an "iTunes" is coming to do it right. My guess is that's Ripple. They have the advantage of being able to take the high road and separate themselves from the black market, money laundering stigmata that Bitcoin has developed, while still accepting Bitcoin as a currency. This is good for Bitcoin and it's last gasp at mass adoption. If the masses are more concerned with low transaction fees and ease of use, than they are having actual stores of wealth, the XRP will reign because an IOU will be sufficient.
am I right in saying ripple has yet to prove itself in the wild?
You're absolutely right. That's why I said "my guess" because they have to prove it, but if they can deliver what they are "selling" it's going to change everything. Again, that's my guess. I don't see anything remotely close to offering what Ripple is claiming to be able to deliver. And until the server source code is available, we wont know.
Bitcoin on the other hand has a wealth of developers and investments right now working on developing the infrastructure, and the decentralised nature is inherently very important.
I wouldn't use the term "wealth of developers and investments" but there is an increase of VC money. That honestly means little to me as VC's by nature expect to fail at most of their investments. I see them as throwing relatively small sums of money into the ring, just in case something takes off. Even Google Venture only put up a couple hundred grand into Ripple. That's pocket change.
The BTC developers could never keep up with Ripple development because BTC developers work on what they want, not what the people want. Ripple is accountable to it's investors and thus must deliver updates and upgrades in a timely fashion.
on the image issue, I think you are right to a degree, but images can change very quickly. Also if you look at fiat money for a minute, do people not use money because it's "got an image problem"? Because people use it to buy drugs?
I don't think the argument that people buy drugs with BTC is a winning argument for exactly what you just said. But on the grand scale when people think the dollar, they don't think negative thoughts. They think, "gotta get more". BTC does not have that advantage. When the masses think Bitcoin, they think negative because that's all they really hear. Now you're right, image can absolutely change and I'm all for it. But who's gonna change it? The Bitcoin community, which is really just this forum in one way or another? I'd say if that's the best BTC has, there's no chance.
