I doubt anyone will give you 1 whole Bitcoin for free today  that’s a lot of money.
But I’ve seen some faucets where you can get 1 satoshi for free, or Android games like https://www.thndr.games/   where you can earn thousands of sats just by playing.

There’s also the Nostr protocol  for example, https://primal.net/
, which works similarly to Twitter. You can post content there, and other users can send you tips in Bitcoin (sats).
