I guess it's impossible to earn 1 Bitcoin easily. In the past, serious amounts can be gained even with faucets, but unfortunately, things have become difficult. Nobody gives Bitcoin for anyone for free.
Think about this:
- How much the BTC will worth after 20 years from now, may be it will be insane. What will be the value of the BTC you will earn now whatever the amount is today.
