Trading is now best way because the price of bitcoin is increasing day by day
So selling might BTC be profitable, buying not so much. I would rather avoid joining the hype and buy now just to catch a rising wave.
I agree with you, now the extraction of alternative coins is thriving. I'm also going to do it and now I'm thinking about which coin is more profitable to mine. But I know for sure that this is not bitcoin
From my experience and the stories miners shared over years I can tell you that the best option would always be simply purchasing coins - not mining them.
At least that was 100% accurate in case of bitcoin mining.
