I think I'll stick with Ripple as far as a payment network goes. As for my go to currency, I'll stick with USD. Accepted everywhere...no questions asked. That said, as long as I can make USD, buying and selling BTC, I'm cool with it.
If the total value of the United States as a country with all the social and cultural capital and assets is X, then the value of the dollar is a representation of this, or X=Y. If X is changing at a rate of A, then the money supply can increase or decrease at a rate of A too and the value of the dollar will stay steady. If the X is changing at a rate of A and Y is changing a rate of B, then, if A>B the purchasing power of the dollar will go up. If A
Right now, Y is increasing at an absolutely unprecedented rate and this is diluting the value of the dollar in favor of the recipients of the newly issued dollars. In this case, those recipients are banks, particularly those holding mortgages.

This makes the balance sheets of banks look a lot better and allows them to continue lending (at a profit, with interest) which spurs growth in construction, small businesses, consumer goods purchases (credit cards). A lot of people, myself included, have wondered how the fed can create so much new money without inflation skyrocketing- and the answer is that most of the money is being hoarded. The Chinese have about 3 trillion dollars in dollar denominated bonds and foreign currency reserves, and US banks have about 1.8 trillion sitting around. If either start to dump their dollars, the market will follow suit and the dollar will crash.
This is basically a financial cold war- if the Chinese start to dump dollars US banks can immediately respond by unleashing a huge pile of dollars too, devaluing the dollar so China gets stuck with a big pile of paper. Notice that the US banks reserves are less than China's- that means that if China tries to dump that the US stands to lose much less- not to mention that in the case of hyperinflation the 17 trillion in US debt will suddenly become much less valuable in real terms, although since hyperinflation will hit the poor hard it would require martial law and a rationing system to allocate basic consumer goods.
The piles of dollars sitting around are basically potential inflation that has not been unleashed. Check it out- if US banks have 10% of the dollars in the world, and the fed increases the money supply by 20% and gives all of the dollars to the banks, the banks went from having 10% of all the dollars to having 25% of all dollars. Or concretely- if there are 100 trillion dollars on paper worldwide, and banks have 10 trillion of them, and then the fed prints 20 trillion new dollars and gives them all to the banks, the banks now have 30 trillion dollars of a total of 120 trillion dollars "existing." 30 is 25% of 120. If 100 trillion dollars are worth 1 trillion bushels of soya(or insert non-fiat commodity here), or the combined buying power of all dollars in existence is 1 trillion bushels of soya, assume that the number 20 in this example represents the amount by which the growth in the money supply EXCEEDS the growth in underlying value.
Banks in the US just went from having the power to buy 100 billion bushels of soya to having the power to buy 250 billion bushels of soya- and all they did was make a ton of non-performing loans!
These numbers are just meant to simplify what I'm trying to say, which is that China has a huge pile of dollars they have made exporting to the US, and the US is using inflation and the threat of inflation to steal that money back. How long do you think China is going to put up with this? They can't do much about it, but they have officially sanctioned bitcoin use in China- and it's crazy that they would promote such an unregulated technology when they are known for being the arch-financial regulators- they are doing so because they know that the more bitcoin is used the more it will erode the dollar. They are also deregulating the yuan so that yuan will start to migrate overseas and they can sell exports directly for yuan rather than having to continue to accept dollars that are having their value quietly robbed by US private banks. They are also buying Iranian crude oil and paying with subway cars since sanctions hinder dollar denominated transactions.
If China gets too uppity, the US has been eyeballing Iran for a while, and Syrian escalation with Iran providing supplies to the side that the US is increasing pressure against means possible pretext for involvement. For example, if the US instates a no-fly zone in Syria a la Libya, Iranian anti-aircraft weapons in the hands of Syrian forces could end up hitting US fighters. This would necessitate bombing supply convoys coming from Iran towards Syria, and eventually provide an excuse for the US to finally try to take over Iran or send piles of those freshly minted dollars to factions inside Iran that will do what the CIA tells them too as long as dollars keep flowing, and force China to keep paying for the oil they need to keep their economy running in dollars, thereby maintaining demand for the dollar and allowing the US to continue robbing the value of China's hard earned piles of dollars.
So really holding dollars is basically akin to hot potato or musical chairs, except that there's a war when the music stops. If you are speculating by buying high and selling low, you are basically trying to beat the market which means take the money from less adept traders. This is not a win-win. There are plenty of ways to make money in win-win circumstances. You are feeding off of other people's losses, and guess what? What goes around comes around. Quantitative easing is basically the biggest rip off the world has ever seen, and everyone holding dollars stands to lose from it- except the people receiving the newly minted dollars.
That happens to include me, since I am a home owner in the US and QE is what enables banks to renegotiate loans without collapsing. That means the possibility to renegotiate mortgage payments to lower rent and increase profits of property owners, which translates to more cash in circulation and increased consumer spending, which leads (partly) to the gains we are seeing in Wall Street right now. (EDIT: Oh yeah, and I think it also has something to do with the good employment numbers in the US, whereas ECB QE is dwarfed by US QE and the Eurozone has major unemployment problems) Money represents work, and the US is getting more money without really doing any more work- and who is paying for this increased value? Where do people work 16 hours a day, 6 days a week? I smell a slave rebellion in the works.
Basically a total overhaul of society is necessary and it means absolute political death for whoever is in power when it happens. This will mean that !surprise! Western liberal democracy will meet the same fate that every democracy in history has met- a slide to totalitarianism. So yeah... if you want to support this scenario, go ahead and keep using dollars. You know that scene in Braveheart where William Wallace is giving the speech the Scottish army- well you could substitute the words "lives" for dollars and "freedom" for bitcoin.
"They can take our dollars, but they cannot take our BITCOOOIIINNNN!!!"
