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. ..
It is not free if you are required to perform any action. But it doesn't make sense to spend your time collecting dozens of satoshi for free, instead of directing your efforts to learning the basics of cryptocurrency. Having received the necessary knowledge, you will be able to earn cryptocurrency yourself, or receive it as a salary for performing qualified work.
