simple, just buy it from an trusted seller
Do you think you can make 1 or 2 bitcoins in that way? You can buy but its just converting your fiat into bitcoins ,What the OP means is how to make bitcoins in other ways .
Making 1 bitcoin with zero balance and in one month. Its going to be pretty hard, unless you get lucky on some gambling sites or trading. But for that you would need to spend a lot of time on the faucet sites.
Forget about faucets, unless you think bitcoin is going to be worth 100k or something, since it is simply a waste of time you are better off getting a regular job and then buying bitcoin with it instead of wasting your precious time claiming in a faucet for a ridiculous amount of satoshis.
Faucet won't do unkess you started faucets way back when bitcoins started and claiming 1btc and higher . And buying bitcoins is the same as on tops post . Well ,there are many ways to earn bitcoins but it won't assure us to earn 1 bitcoins in a month because it depends in our skills and ways like investing in trading or playing gambling which can make our bitcoins grow .
