You can just earn bitcoin from completing tasks like watching ads or even completing surveys. Most of them are scams so be alert. You can also just claim faucets these work 100 percent.
So just go claim faucets.
Yes i agree. I mostly earn my bitcoins from claiming from faucets. I a few years ago did watching ads for bitcoin, but they didn't pay me they even don't care about you. You are just making money for him a lot of money, but he doesn't give any money back.
