Bitcoin is already a success (just the price doesn't really reflect that) and bitcoin already is there on quite a lot of emerging markets.
I would like to politely disagree.
Bitcoin is currently a success in the same way Linux is/was a success: in a very tiny niche (geeks, sysadmins, tech-savvy folks, etc ...). Unfortunately, Linux never came out of that niche. It's still in there 15+ years later
In the same way, Bitcoin has most certainly not reached the mainstream, and especially not in emerging markets where most people only have old "feature" phones and close to nil in terms of technical skills.
To do so would require a order of magnitude improvement in ease of use, speed of confirming transactions and number of transactions per second the network can handle.
This is a giant missed opportunity: the next 4 billion people who are going to come online are from emerging markets, and bitcoin is simply to hard/too slow for them to use as compared to the alternatives outlined in that presentation (especially towards the end).
What bitcoin needs (especially for its price) is to increase the awareness everywhere on earth, because even if it's there, not many actually know about it, what it is and what can it do.
What bitcoin needs is to become *way* simpler, and *way* faster. And it also needs a client on older phones (non-smartphone).
If it does this, awareness will just be a byproduct.
