only 5$ u can make 1 bitcoin 1 day . Use 5$ to buy a knife, then go rob the bank, ez money ez life
That is a way to ruin your life not to make 1 bitcoin, Obviously OP is asking for a way legally not illegal that can make live behind the bars.
I think that actually the best ways to make some bitcoin online is to get enrolled in a signature campaign or to "sell" your skills. If you know more that a language you could do some translations, if you are fast at typing you could solve some captchas and get paid or if you are good at weiting about something you could write articles for some website.
Signature campaign and selling your services are a good way indeed but if you don't have a higher rank, your sig camp is not a high paying one and you sell services by doing captchas. I doubt that you will earn 1
BTC in 2 months. People who have a priorities in real life have a limited time here so choose a really worth it job because your time is precious.
