Aside from joining a number of online communities especially Crypto communities, you also need to make sure that you are actually engaging in the community and participating in the discussions as well as earning some rewards for your participation.
Some crypto project communities for instance want their members to give their time, attention and eventually their money, in investing in their project. Thus, some projects strive to make their community worth the while by creating competitive events and offering amazing rewards for participation.
I belong to a number of online communities, and I've had friends that had once or twice earned a good amount for inviting members to a community. I think everyone is familiar with referral bounties. Yes, that's it! It works both for websites and app communities.
Recently I found announced on the Bitget exchange community that new users who joined both their Global Telegram and Discord community and send a greeting message with #BitgetConnect get rewarded with the BGB token. I wish the reward was for exciting user like me. Although community members who share the official announcement within June 3, 02:00 – June 11, also get to receive rewards.

I like how community members are taking advantage of these events to earn extra tradeable tokens.
There are many other ways people earn from online communities, do feel free to share some of them and possibly the communities, so I could take a look. I like rewarding communities.
