Reddit even though being one of the biggest online platforms isn't that popular in the minds of people, I am there on reddit but I hardly even remember that app like I do with telegram, Twitter, Facebook, TikTok and the rest, and the app itself is hard to navigate for many users, this is possibly why they are not pulling as much daily active users like the other social media platforms I mentioned initially.
Some subReddit are very popular, like the games subreddits, bitcoin, eth, etc...
I think every social network presence has its own importance for a large business such as betfury.
Maybe some promotions, giveaways and campaigns there could make it active again.
