You are correct in that it is still somewhat profitable, but as I said it will not be the same going forward as it has been during the past 12-18 months.
The run-up in coin prices helped to mask the corresponding run-up in network difficulties for nearly all coins.
The run-up in coin prices CAUSED the run-up in network difficulties - with some delay as it takes time to aquire parts and get systems built.
That period of delay is when profitability surged - but at this point network hashrates are getting pretty close to caught up with the prices, especially with the price DROPS the last month and change having slightly exceeded the "January 2018" surge for most coins.
I would argue that the mining difficulty was going up all along, but no one is arguing that the run-up in coin prices did not massively accelerate this process.
That is the fine detail everyone overlooks now, is that they assume the difficulty will eventually start to fall in order to match the lower coin price. It may, but there will be a long lag time as there are too many people expecting this to be a temporary pullback before the good times are back. I don't think reality is going to set in for most people until they get a couple of months of break-even profits, meaning mining revenue == electricity costs, or even experience a slight loss.
There are now too many large players who no doubt are getting the lowest electrical prices they can find who will continue growing until the break-even is just about at neutral. This will keep pressure on the difficulty from going down, and if the ETH ASIC rumors are true then look out as all GPU coins will suffer the fallout. So if you have access to cheap power you can probably ride out the dry times ahead, but I think anyone paying much more than a couple of cents/kwh for power is going to be driven out within the next 12 months..
