Brian Armstrong, the CEO of Coinbase, tweeted that he would pay $100 to people who provide the “best examples” of using cryptocurrency in Africa, with the hashtag #CryptoAfrica. However, despite more than 600 likes and 100 retweets, Armstrong appears to have ignored the submission of Joe Hall, a reporter at Cointelegraph. Hall shared a video of himself using Bitcoin in Africa, part of a 30-second segment of a recent Cointelegraph documentary covering Bitcoin in Senegal. The video received the most likes and shares but was overlooked by Armstrong. Hall reached out to some key opinion leaders, creators and influencers within the Bitcoin community to amplify the tweet. After some conversation, Armstrong eventually sent the money, but here is where things get strange. Armstrong said he paid Hall the $100 but sent it to the wrong email address, despite the fact that the address was clearly a Lightning address, rather than an email. There are concerns that the Lightning Network may not be on Coinbase’s radar.
