Bitcoin cloud mining services are still being advertised, even though mining difficulty and competition have increased a lot over the years.
Is there a chance that it exists in a legitimate form for Bitcoin today or it's nothing but marketing and scams? I don’t need any advice or names of specific projects, just your view on the current state of this area.
Are you referring to Bitcoin mining by renting mining hardware? or, cloud mining which is similar to a Ponzi scheme?
Well, if you are referring to Bitcoin mining by renting hardware, I remember there was a discussion on the forums, and maybe it is legitimate (Some of the discussants seemed to have tried it before), but some argued that the hash rate obtained was unstable, which would affect the mining results. They argued that the rental price was very expensive, and some even compared it to other rental sites. However, You also need to re-clarify the truth, it could be that the site mentioned earlier is no longer legit at this time, keep dyor. For more clarity about the discussion before, please see the following discussion :
MiningRigRentalIf you are referring to cloud mining that requires deposits, or performs unreasonable mining (it has a Ponzi scheme feel, or something like suggest you to find a refferal to speed up your gain), then I suggest you don't try it. I have signed up for several such sites in the past, and you know what? They are all gone now, and I haven't even made a single profit, it is as if they are deliberately making it difficult for the withdrawal target, and as if there is a motive behind it. Luckily, I have never deposited on any of these sites, as I find them extremely risky, and you should be aware of that as well. I think almost all of them are scams, or maybe all of them are scams, idk. If you find something like that, it should better to avoid it, or you can tell us here so we can discuss it together. Cmiiw.
