No ASIC is profitable in short term. ASIC´s are always for long term mining.
You are wrong it depends on the price for the ASIC miner, if OP has free electricity he can just buy old ASIC miners, old ASIC eats lots of electricity but they are lot cheaper than building a mining rig full of graphic cards, the power consumption side is why I don't buy already
It is clear that it depends on the ASIC price, and now give me an example for an ASIC that is profitable in short term!
Antminer L7 for 12000$? Not really, Bitmain S19 fo 9500$? Not really, Bitmain E9 for 25000$? Not really. So in the end no ASIC is profitable in short term at the moment!!!
There are no free electricity for no one, because someone must pay the price and if use solar energy -> the solar panels are not for free!!! And by the way the OP has no free electricity, so why you talking about this?
Hi, someone in my country is offering me innosilicon T2 ASIC miner for 750$ each, this person is a very trusty personal from China and I've got some graphic cards through him before, this T2 can do 17TH on bitcoin mining but power consumption is 1500+ watt which turned me off, just want you to know that some ASICS are cheap and good for those that have free electricity
