Excuse my ignorance since I personally don't do mining, but is the potential profit of mining still THAT good? I know the price of btc/eth is increasing, but doesn't the increasing mining difficulty have a huge effect on the potential profits from this?
It used to be barely profitable when Ethereum was around $13 for a long while. Now that the price has rapidly spiked up, the total mining power hasn't spiked up accordingly. This means that the profitability has increased significantly. Currently, its quite profitable, as long as you have the mining power for it to be stable. It's as if you were mining with the first ASIC..
Im not sure how long it will stay like this, though. Cards are constantly being sold out, and the price isn't rising as sharply anymore. Maybe it will be less profitable after time.
