You might have heard of a blockchain built and developed by an African ( particularly a Nigerian) the name was inksnation(pinkoin) it it has over 1million mass adoption all over Nigeria. It has a plan of paying every member $4 daily so many Nigerian's sign up for it little did they know DAT their plan was far from reality.after its launching on the proposed date which is August 12th 2020.the site started having serious issues beginning with login problem, lost of password and even inaccessibility of the site on some browser. After sometime the block chain couldn't pay its members cash as it has promised. 

 The CEO of the blockchain came and assured the people that everything is and will be ok, that it was a system upgrade. He later assured them that the site would be going on a 3months system maintenance even up till now.

 After some months ago he was declared wanted by the Nigerian EFCC(economic financial crimes commission) of which he was later arrested. Although most Nigerian foretold it was a scam. But the CEO of the blockchain insisted DAT it was just some alleged plot by his haters in government trying to bring him down because he is trying to make life better for Nigerian's

  Still even till today Nigerian's are waiting for the come back of their first blockchain. Hope this dream becomes a reality for them and all of Africa.
