Bitcoin mining with cloud hashing

Cloud mining is good because you do not purchase equipment, and invest in the rental or purchase of facilities. You need to act according to the following scheme:

Select the sites of cloud mining.
Register, Deposit bitcoin into the account.
Purchase as much capacity as enough money.
You mined Bitcoin with the rest of the miners. Profit for the cracked hash will be split between all users, but taking into account your investment amount. So you will earn less than a classic hashing, but the chances to profit hundreds of times higher than it is in those who work in the team. Bitcoin mining can be performed at the following sites:

TopMine. The service gives you possibility of earning with a minimum investment of just 0.001 Bitcoin. You can also use the gift 5TepaXэш.
HashCoin is another relatively inexpensive project. You can invest only 0.003 Bitcoin. As a present users get 5ГигaXэш.
Ahash for those who have the ability to invest more than $ 6, the minimum amount of investment is 0.01 Bitcoin.

If you are ready to invest we offer the best sites for mining Bitcoin with cloud mining free of charge:

BitcoinCloudOnlin give 50 Gigaherz.
BilyOceans provides 1000 Kiloherz.
It should again be noted TopMine that pleases you record free 5 Terhas.

Those "cloud mining" sites you just referred to (after doing a google search on them) seem to be more like HYIP or ponzi type sites. The only real cloud mining sites where you can either rent hash power and direct it to a particular mining pool are genesis mining, hashing24 and nicehash.

When something says you are "cloud mining" most of the time they are taking bitcoin from new users or referrals and giving it to the older members as a ROI for them to keep them happy and referring new people.

Admittedly I didn't do much research on those three sites you named, so I'm not going to call them "scams" per se (because there is probably a way you can get money out of them) but they would become scams once they reach a certain level where the operators either have collected enough btc that they want to stop or they can no longer pay for interest on the current deposits from new members joining.
There is no such thing as free hashing power, that is just a gimmick.
