Check this - www.sportstalksocial.com - This is a crypto/ purely sports related community with around 1000 members right now .

It comes under HIVE ecosystem so obviously 1000 isn't the actual userbase ( far more than that ) . you can go here to take a look at my blog - www.sportstalksocial.com/@amr008 .

Let me know if you are interested , thank you.
