simple, just buy it from an trusted seller
It's not that going to be an easy thing, he wants to earn the easy way without even pulling some withdrawals from his bank account or with his personal money. This is just good for those traders or bitcoin newcomers that has enough money to do so because if you don't have this amount it's better to get it the usual way as others are stating.
It is easy, just find yourself a good paying job. Save part of it according to the calculation where you can buy 1 Bitcoin after 2 months. If your job is not enough, find a side job to add earnings. If you cannot find one then you cannot buy Bitcoin even after 2 or 3 months and give up on the idea of owning 1 Bitcoin after 1 or 2 months and reassess your capability and set another target time range. Much better to set it in 6 months time.
With what the OP wants to happen, he will just use a very small amount of his time on a daily basis. And I guess that is not going to be enough to earn this monthly income. But if you will going to give up looking for the best and high paying jobs then you can possibly earn this amount or if you can't , maybe you are close on earning this.
Correct OP needs around 10 -20 bitcoin for capital to earn that amount in monthly basis because bitcoin earning is always base on the capital investment if you put large capital your potential income is also big.
And for now the job with potential to earn that 1 bitcoin monthly is being a campaign manager with multiple signature campaign handled.
Yes, possible 1-2 bitcoins monthly earning will need a lot of bitcoins and capital. But I really doubt it that op is willing to invest that amount or he do have that amount. Even me, I don't have that amount monthly but it's better to earn with the capacity you can even though that is not that high but as long as there is gain, that's fine.
