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.
i ask you again, how much capital do you have to start a bitcoin mining business, if your capital is still tens of thousands of dollars then bitcoin mining is not suitable for you. it is much better if you become a bitcoin holder, you do work or business out there but still buy bitcoin with the DCA method, surely the profit you get will be much greater than you bother to become a trader or miner.
