I have met with bitcoin experts just to get as answer to this question but it ended up in an argument, i need to know were to dive into.

btc trading or btc mining

which is more profitable.
Your question is good one, but I want you ask you, are you asking this question base on asking seek or you is something you want to practice one among the two?
Because its clear that many people don't go into mining because it requires powerful electricity [current] which before you can set up the gadgets for mining it will consume you a lot of funds, so that's why I asked you the question above... For trading, is a skill you can acquire and practice, and for you to make a profit during trading it depends level of your understanding on it, so comparing trading and mining, I think that if you have what it takes to establish mining plant, you will be profitable from mining more than trading...
But if you want to make a profit most, I think is encouraging for you purchase bitcoin and hold for long-term, that will propagate well than trading, but holding is not in your options.
Some people think that Mining will be a profitable option here, but it really depends on which country are you in also how high the electricity cost in your area since that adds up the factor if you can earn or not from your operation. Plus we also need to consider how expensive buying those hardware then its maintenance cost so everyone thinking about running want to mine should do a lot more research so that they will not throw their money and regret on why they decide to do it.
Both option is so risky but if OP would just do a research and try to be get more knowledge on those things what he want to go through then provably that he can earn some good income especially if he is committed and willing to take a risk on those options he choose.
