Hello Philip,
People tend to send their first intro post in #introduceyourself. I think this could be one of the reasons you have not received many upvotes yet. They also tend to send some sort of verifications. Photo with your username or date, etc. Many ways to do that. Promoting Bitcoin in Africa is a hugh task and very beneficial for the communities especially in rural areas. I like what you do and hope you are real because I have just upvoted your post! Educating young entrepreneurs on STEEM would be also a great way to find business opportunities. Cryptos will be more mainstream in the future anyways. I would be delighted to see young ambitious people rising from poverty and finding new opportunities because of blockchain and cryptocurrencies.
I wish you the very best!
Andrew
