Yesterday I discovered another way to get bitcoin - freelance with payment in crypto currency. And he was surprised that a good reward was promised for such work. This is mainly the IT sphere
The other way where you could a good amount of bitcoin is advertising ads on your website, well, making one is not that hard if you have backgrounds on the programming language that you are going to use to make one. I've never try this before but my friend already have one, and I am telling you that he is earning a big amount of money on it.
Signature Campaign is also one of the best way where you could earn bitcoin, especially in the Altcoin sections, if you are going to be lucky and joined an ICO which made a very huge fund, then you are going to have instant money on it.
