I feel very inspired right now. I just came across a video in which there's a Bitcoin ATM in the country! I feel so glad to see how Bitcoin is getting adopted. This proves that after all, our promotion of bitcoin is helping in spreading the news. And we aren't planning to stop the promotion anytime; we're even planning to hold more seminars to help people know about bitcoin. Now, one of the advantages of this Bitcoin ATM is that anyone who doesn't know what Bitcoin is and sees it would ask what the machine is used for, and from there, it just keeps spreading!!!
Watch the video here to see how it works. BTW, What progress is happening in your country? If none then try doing more in favour of bitcoin (for countries that find bitcoin legal).
I don't really see it as adoption, it's more like enabling the Nigerians to get some BTC in an easier manner. A little but sweet development for BTC in your country, and I'm happy to know you've now got an option to purchase and sell in a physical way.
It is just the beggining maybe we cannot literally say that it was an adoption, if more and more people become aware about bitcoin they will probably try to buy some of it and maybe share the news with their friends or in social media. In this case we can generate mass adoption and finally if more and more people buy bitcoins to the price of bitcoin will go up.
