Even if you have free electricity ROI is hard to reach if you spend money for miners

In 4 years with free electricity, one still may not make their money back? I'm personally not a miner, and I understand it's too late in the game for the general population to get involved... but that sounds ridiculous. With free electricity, OP still shouldn't expect to turn a profit?

It is actually possible to not reach ROI even with free electricity.
I'm fairly certain any method used 4 years ago couldn't even get a single share in a pool or solve a block alone right now.

However, unless you buy a really outdated miner or difficulty goes up incredibly fast, people should be able to ROI in about 6 months (very rough estimate).

Well if you buy S5's for 1.5k USD a piece, then i guess its possible, but unless you do a terrible investment, i'm pretty sure you can ROI any current miner and old gen decent miners like S1/2/3/4/5 SP's and Avalon.

I think you mean S7's. But the argument there is efficiency that it could mine twice as long as lets say S5 on same electricity remaining profitable. It in most cases will be more then 6 months. 3 and even 6 months are pretty much done unless "free" electricity and old gear like S3 which have gotten very cheap considering you still get a good miner.

But long term S7 (as long as you dont have crazy VAT, or high electricity) should ROI if difficulty does not go crazy. Some ROI might include selling the machine to get that ROI. But likely with mining and selling I see most who did the math before hand ROI. Like I said if you have 25 percent vat or .15+ electricity then yes most likely you lose. (And were getting close to winter so I'm sure some will say a little loss is for heating rooms but that highly varies)

No i mean S5s. Since what i'm replying to is someone saying it can be possible to NOT roi in FOUR(4) YEARS with free electricity, you'd have to do a majorly bad investment in which miner you pick and which price you take them at to NOT roi in 4 years.

I just don't see how you can not roi in four years with free electricity.
