All in all we can say cloudmining and hosted mining is just not profitable because we have so many middlemen costs occurring. You will be charged to have operations funded by a maintainer who will always charge a cost to stay in profit for himself.
Not just that. Majority ot cloudmining doesnt reallt operated with the specs or gadgets shown on the website.. What does it mean? They are just simply using the website and the image crafted for the newbie to get on with the site and invest money on that. After a while they can do like the users earning showing it and let them withdraw at first but when its famous already they will start planning to exit and scam the money. Tsk
The above is just for random scammers and not necessarily any cloud mining services. The internet space is porous you know and anything is obtainable. There are still reputable cloud mining platforms like Genesis mining, Binance pool and Ecos
I do not think cloud mining is the best with respect to profitability. Hosted mining is better as long as you have enough capital to buy your own hardware to increase hash rate which is very expensive and more reason only big companies are obviously profitable in the business.
If you have the upfront investment and wish to be in the business for longer, hosted mining is the best as long as you are working with more reliable hosting providers
