Yes, the figures I get from whattomine seem much closer to the figures I'm getting.. still a bit puzzled, all the altcoins I simulated there are not profitable at 0.1$ electricity cost, which is already cheap electricity. So the question then is - how is anyone GPU mining if all these altcoins are unprofitable??
Google did not provide any mining estimate, maybe you're reading some old articles or old profitability pages.
As already said here, whattomine is the best source to at least get closer to real profitability
And yes, mining is not good right now, maybe it's the worst time, it's pure math, with 0.10 USD kWh you'll mine at loss.
People will continue to mining and there's a lot of reasons like solar panels, dirty cheap electricity, long term projects, coin supporters or just people mining at a loss, holding the coins to sell next bull run.
So, the problem is not you or your GPUs, the market are bad and mining is not giving profits to us home miners.
