Nowadays its so hard to get 1BTC of Bitcoin. I think the most possible way to earn 1BTC is by freelancing, if you know how to make websites, do graphic designs. This is possible.
This is what I keep on saying especially with those people like OP that doesn't want to invest. Because this amount is truly hard to get if you don't have something to offer or to sell. But if you can do a business like buying and selling of the things that you've got. Probably you can earn this amount if you can have good volume of sales.
Yes you cannot earn 1btc or 2 in a month by not doing much. you have to make sure you learn more about btc, once you have good idea about idea then try to trade which is risky but at the same time possibilities are you will earn more. otherwise if you are skilled at animation or gaming or web designing then you can do some freelance project which will give you the best in return.
Trading isn't enough if you are not willing to invest some capital on it or you don't have a bigger capital. I prefer the web designing and other programming skills because they are in demand. But animation is also good, the best way on earning is none other than being employed.
To earn btc 1 or 2, the only easier way is to learn the programming language or do some graphic designing courses and then get the benefit from here. if you have money then invest in btc as the price is low now and after sometime the price will up again so that you will get good profit from it.
but you are left with less options if you are new to the btc to earn 1 or 2 btc untill you have knowledge about btc or you have good skill in some subjects.
