I am doing OK with trading and poker for last 1-2 years (making average 40$ per day) but my income is declining simply because I have stopped putting needed efforts. I have become bored with poker specially and I don't think I can do better in these field.
Hereby I seek the knowledgeable advise from you guys. may be you can help me out in shaping my future.
Poker is not a source of income as it can burn you with a loss at any time. Given that you are a sociology major and not a major in finance I wouldn't rely on trading to keep you afloat in the long term.
I'm in the same boat as you, and in my opinion mastering a completely new skill will take too long if you just need the cash, I would suggest offering your services of blogging about sociology in the services section so you can at least get some money in bitcoin.
