How can africa adopt bitcoins if they are porn and cant afford smartphones and good computers?
It's only a matter of time before even the poorest of nations have widespread access to smartphones and good computers. Moore's law is a wonderful thing. In 2010, it was pretty damn near impossible to find a smartphone for under $200 here. In fact, this was the phone I bought in 2010:
I was able to buy it for $200 and it was selling for $250 elsewhere. It had a tiny resistive touch screen, 240x360 resolution, no Android, no wifi, and wasn't even a smartphone despite its looks:
Despite this, it was one of the cheapest phones with a touch screen at the time.
Today, that same $200-250 will get you this magnificent beauty:
That's a 5" HD screen with quad cores, 8 MP rear camera + 2 MP front camera, and running the latest version of Android.
Even the $80-100 phones are pretty good (in fact, this is my current smartphone):
And here's what $30-50 will get you (still better than my 5 year old $200 phone):
The latest Raspberry Pi is 6 times more powerful than its predecessor, features 1 GB of RAM and a quad core processor, will run the latest Windows 10, and only costs $35. I've seen tablets with HD screens and dual core processors go for under $80.
As I said, it's only a matter of time.
