Good job and I wish you good luck in getting rid of that dark smoke around you. At least investing in bitcoin wont kill you in later life. I also use a part of my monthly earnings to buy bitcoin as a mode of increasing my stash of coins.
I also earn from trading - mainly bitcoin vs fiat, altcoin trading and altcoin mining. You can see I also am enrolled in a signature campaign which pays me well every week.
Not to mention, I also earn from campaign and other micro jobs, but I'm looking forward to taking a bigger risk for bigger rewards and hope it will happen the soonest possible time.
Trading will give you better results in compare to other ways of earning but its good to start trade with descent capital to get promising results so once you have accumulated enough bitcoins you can invest that in trading and start making good profits and earning from signature campaign can be a good source of extra income which can take care of basic stuffs.
