There are soo many methods to receive bitcoin, just like our normal fiat. You can offer services with your expertise or skill and collect bitcoins as payment. You can trade, purchase and promote everything and settle for bitcoin and you can mine. You can be a part of signature campaign below also or join ICO with legit dev and so forth.
I prefer to get bitcoin results from participating in champaign signatures, because it is not too difficult to follow.
and in champaign signatures I can appreciate my own work or can share in bitcoin to everyone.
but when I am really in financial trouble, I do trading activities that can make money faster
