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.
You have gotten your answer. The Bitcoin miners and traders in this forum all hold Bitcoin, that's the interested part of been a person that loves Bitcoin, if you then have any other things on your mind to do, then you can use that as a secondary income. However, if yiu call a trader and a miner to share their opinions on how profitable it's to be one them, there will be a trader that will say it's the best and there will also be another person that will say miner is profitable.
Here is my take, if you want to do trading, you need time on your side, you will always be there as a full time trader if you really want to make the money and you will have to risk a lot but as a miner, you don't really need time on your side once your set up is completed. You just have to make sure your electricity is working 24/7 and your rigs are working as well, you need to make sure your rig have a high thoughput hashrate.
