Okay so earlier I came across a site that claimed that it's possible to get bitcoins for free by just; playing offline and online games, watching ads and videos, participating in airdrops and so on. They also recommended apps that give out bitcoin for free  like coinbase. Bitcoin, ranked as one of the most expensive cypto currencies can be earned for free by just watching ads? Nah I just find it hard to believe cause I've seen a lot of scam related schemes that claim to give out bitcoin for free. I don't know, I might be wrong cause I'm still a newbie that's why I brought this here, to see if I can get some clarification on the matter. Thank you.
