Wow... incredible ignorant answer before me coming from someone who never traveled the world. You can make low cost world wide transactions at a heartbeat... that a great technology and product and has changed already millions of lives who have been disenfranchised by banking system.
What's next? Well I'd point to bitbay.market you can trade anything with double deposit escrow and it essentially can replace any notary system in the world. And the dynamic peg can make it a true store of value, without relying on any other asset to back it.
That's just gambling and speculation in my opinion. BTC-fanboys are often throwing that "financial inclusion" argument, but where are all of those people? Why aren't they just using PayPal? And before you say something like "they can't because they don't have credit cards or bank accounts to connect with PayPal", then how the hell do they swap their received BTC back to their local currency again? Additionally, just think of the volatility BTC shows us everyday! If you're unlucky, your transaction will be much more expensive than Western Union or comparable options.
These people are everywhere. Only because the majority of the people are blind to world issues does not make them non existent. Risk mamangment of Banks does not allow many to open accounts with people who have no income or little income, or not adquate ID. Not even Western Union serves rejects many people. Sure, there are pay to go debit cards, phone credit solutions and these people use and of course tons of other methods, such as simple cash or valuable items. Bitcoin is just one of many, and yes, I totally aggree that the volatity is a huge issue for day to day workers who can't risk a 5% change in price when sending money home to their loved ones. However, you are coming most likly from a first world country with a stable national currency. Talk to someone with rupee, brazial real or venezuelan bolívar. The risk reward is relative.
Hence I mentioned bitbay.market here, since it offers an unique value propostion to be a "stable coin" that does not rely on a central authority (which we know fails on average in 26 years intervals. Check average life span fiat currency, and the only reason the average is so high is because of the British Pound, which actually had multple reforms to sustain it's existance).
However... I can confirm from first hand experiance that Blockchain is certainly really changing the world. I personally helped thousands of people who would have otherwise never had the means to make fast, low cost, transnational transactions or even start entire buisnesses. And I can tell you that bitbay.market is going to change the world even more as soon it's "dynamic peg" goes live in too soon future.
I get your point, don't get me wrong, I think financial inclusion is one of the most urgent challenges mankind's facing by now.
But I still don't see how people in poorer countries benefit from a transaction in some cryptocurrency, as they can hardly pay anything from it without changing it into something locally accepted, like a rupee, brazil real an so on. I'm just curious about how they swap that digital currency without paying a lot of fees or using semi-legal exchanges.
What makes you think they can hardly pay anythign from it? There are huge networks we simply have no good metrics to messure them because they are informal buisnesses. You can call it also at hoc economy, or unreported economy. Just take this number I pulled from wiki. "In the U.S. unreported income is estimated to be $2 trillion resulting in a "tax gap" of $450–$600 billion."
Are real issue is fraud, scams, and security, people thinking they are buying bitcoin but ending up with some shitcoin. Also overcharging is a huge problem. That's why education of what bitcoin really is and how to use it safe and sound is really important but ever since the marketing people came into the game and wanted to make bitcoin mainstream... that learning curve got washed away... sadly. Greed has taken over.
Well... just my few cents for now.
