Earning money without investing is actually quite hard. I suggest you to go find a job and work hard. If you have skills like coding, you can go to some freelancer job site and offer your skill. It takes time to make 1 bitcoin per month at your current state. So as i said, the most easiest way is to just work/ find a job and convert to bitcoin. And if your converting to bitcoin with money, you are technically also investing as bitcoin prices will go up and down. Good luck earning your bitcoins, work hard and never give up!
In my county if you want to earn 2 bitcoin through a job. So it means you have to word for more than 12 month even if you are getting a high salary, but if I am sure that even if you have a small investment and you do trading altcoin from there you can make 2 bitcoin less than a month duration and especially if you have good study and experience about the crypto market.
Then the bitcoin industry is surely for you. You can earn 1
BTC from an altcoin signature campaign if you get lucky. You're lucky to be here because earning 1
BTC from here will be a huge thing for you. I suggest that you go full time here and study trading. There are also other ways to earn bitcoins by providing service like photoshop, designing, programming, and whatnot.
Trading that gives you 2
BTC for less than a month will require a lot of money which I assume you currently don't have based on the pay rate of the day job in your country. Others invest in ICOs too because of the early investor bonus. A couple of days ago, this happened. Primalbase token is 5
BTC each but for early investors it's just 3
BTC. Their crowdsale has ended in just a day. Let's see if these investors will actually earn money considering the fact that they all bought at 3
BTC. I know that all of them will just dump the coin right away.
