Earning a living with BTC is like working in a bank that will soon go bankrupt.
There are few reasons why BTC is not reliable for earning:
1. BTC prices vary very fast and can make you rich or bankrupt in a day.
2. Gambling is never edged towards your side. The longer you play, the more you lose.
3. Earning online is not something to be proud of nor will it get you a good profile.
4. Trading is very risky and cloud mining is slow and unreliable.
