No they haven’t been around for years since people figured out that cloud mining is another name for ponzi schemes.
It is actually kind of surprising people stopped using them and let these scams go bankrupt. Hope in humanity is restored. Maybe the majority is not as stupid as I thought.
No, there are still many, and they mostly promote it on Telegram and Facebook; you will not find it unless you look for it.
Personally I have never found a legit and trustworthy cloud mining, all I found were scams and seemed promising when in fact they were just trying to find a target victim by making a deposit, instead of getting profit the victim only experienced losses for several reasons such as no payment or even the disappearance of the cloud mining service. You should avoid services like this. I prefer to mine Bitcoin on a pool or use the referral system on a trusted mining pool site to get profit, rather than trying cloud mining.
Have you heard that Binance have cloud mining service? They are selling hash rate, and Binance is a trustworthy exchange.
There are two more Nicehash and Miningrigrentals are selling the same service and they are still around for years.
