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.
They are all profitable, and you will find successful people in both sectors. Successful individuals in trading may have the opinion that trading is more profitable than mining, while other successful individuals in Bitcoin mining may claim that Bitcoin mining is more profitable than trading, but for someone with no knowledge about Crypto currency in general the most profitable for them will be just buy, invest and hold Bitcoin.
So that will depends on how they really know about trading, mining, or hodler. Yes, they will say that is profitable but if we don't know anything about trading and mining, we should choose the last option which is become a hodler.
That will be profitable because we don't buy any mining hardware which needs a lot of money and we don't lose from trading. But we only hodl our Bitcoin for some term and sell it in the bull run. That will gives us the profit.
The only thing that you must aware from hodling your Bitcoin is controlling your emotion because you will see the price change time to time.
