Nope. You can earn 1 bitcoin in a month even if you dont have money try to join signature campaign here in the forum and earn some bitcoins and use it as a capital for trading altcoins. You can offer also your skills here in marketplace 1 bitcoin is possible.
But signature campaign earning is not so enough to start altcoin trading and make 1btc.Again,bitcoins price is in 1000$+ now.So its became more difficult to make 1btc in a month without investment.If you have skills like designing, programming, developing etc then you can easily make 1 btc in a mmonth.
