Profitability is surely low but is it actually low?
We mine because we believe that in future the crypto we are mining will give us better returns. So mostly it is about holding for long enough that we gain whatever we set out to.
You really need to start thinking in terms of BTC / ETH /whatever you are holding instead of fiat if you want to mine/trade crypto tension free.
good point
https://www.nicehash.com/miner/16yLHLoeyuCLPMXkVpC3gyrRYvwRGwjKJrthis account makes 0.0099 btc a day or 3.65 btc a year
If I mine and hold all that matters is the price of BTC 1 year from now.
But this gear is paid off fully
the power cost is zero as it is all run on solar energy
Thus I can mine and hold for an entire year. If I need to do that.
