New Delhi, Jan. 28 -- American streamer and YouTuber IShowSpeed is on the final leg of a 28-day tour of Africa aimed at showcasing the continent's cultural diversity, which is often overshadowed by images of poverty and violence.

The 20-nation tour across southern, eastern and North Africa began in Angola in late December. He attended the Africa Cup of Nations soccer final in Morocco on Jan. 18, then visited Senegal, celebrating the national soccer team's victory with fans, and Nigeria, where he passed 50 million YouTube subscribers and marked his 21st birthday.

"I've done so many incredible things in my life," IShowSpeed said during a stop in Botswana. "But this trip is different. It opened my eyes. Africa is not what I thought."
