but trading too will make you earn btc...
Even you are not a developer you can earn this amount with other types of freelancing job. But with OP's situation, he don't want to invest.
Because that's the other way that most of us can see in able to earn this amount of bitcoin for a month.
Trading is a yes, because it will generate you good amount monthly if you can have a very good signal with your trades.
And you can earn up even higher.
Freelancing jobs will not give you permanent income I guess as you will have to complete the task in certain time frame and may be after that you don't find any job related to your skills so and to find any other project it may take time but trading is a good way to have constant income.
