why would you want to cloudmine bitcoins nowadays when so much websites turn to scams and it is so unprofitable
I agree with this and it is basic common sense. This of it like a real mine. If you have 10 mines making you $100 per day each, you are making $10,000 a day letting them mine for you. Why would you lease these mines out for $90 a day each just to loose $10 per day. Cloud mining is useless and does not add up.
The reason is they have the space and can get a quick profit. If they can make ROI and build even more by selling a miner, that is smart buisness. Instead of months to get ROI they can do it in a day... that is a lot of saved time. And they I think make a decent profit off sale and then they make profit on running them so creates a monthly income on a new source.
So this if anything allows them to get bigger in most cases. And at end most own the gear... so that is the cherry on top for these sites. Look at hashnest it is very popular. I know I like to get the gear as I enjoy tinkering with it, but for all is not a possibility. So sites like hashnest do serve a purpose.
