This is going to be a very interesting topic, if we can get anyone to comment that truly understands the concepts behind Bitcoin and other Cryptocurrencies. I agree that they are much safer and to a source they could provide a safer transfer and no money trail, that is one of the biggest worries is the illegal activity that could unfold from Bitcoins catching on. I am not a bitcoin expert, but I have looked into investing in them and I ended up backing out. The concept was way to much for me to grasp and the volatility was risky, although some made a lot of money taking the risk!
Bitcoin is a very hard concept to grasp for a normal consumer as of now, in the future it may become easier, but I am sure anyone that has looked into them has had a rough time trying to understand the concept. Bitcoin is also very unsecure, there is very little insurance on your coins, so that leaves an open space for hackers and shady dealers. You can not reverse a transaction once it has been conducted, so anyone could claim they are selling you that super juicy gear and then you send them the coins and then POOF! They are gone with all of your virtual currency! This also leaves room for hackers, they are becoming more and more common as technology advances! Everyone saw the hacked iphone photos of Jennifer Lawrence right??

I honestly wasn't impressed, but anyways you could also argue how safe that money is in your wallet with all of the theives/crooks running around.
Bitcoins are also very volatile right now, they have been going down in value over the past year, but they are making a slight rebound right now! At the beginning of the year they were around $1000 and now they are around $400 from a quick google, so it seems they have found a good leveling area considering where they started and where they bottomed out after the rush. This leads into another point we could look at, would it be worth it to the source to take bitcoins due to volatility? There is no central authority over the value of a Bitcoin, so lets say I buy for $400 and the market drops on what they are worth to $300 and the source is left holding the bag. It's very common considering in late 2013 The prices for bitcoins were well over $1000, so would that risk be worth it to the source? The source would also have to sell the bitcoins to recieve the funds, because what is he honestly going to do with them as of now? I'm not saying it couldn't happen, I am just saying that as of now it is just not practical.
Making the coins is a whole different kind of beast.
I believe that something like this may exist in the future, but as of now it is just not practical. It may be to bigger companies like Amazon and other .com buying sites, but to some company/group making good gear is may not be the way to go.
Who knows though! A very interesting topic, hopefully someone with more knowledge will chime in and give us the DL!
