Mining bitcoin and other crypto-currencies can be a large investment today. To allow for anyone to part take in the process some companies have made a business of renting out some of their hashing power.
By doing so they can make an immediate profit and grow faster than if they relied on mining alone. Clients, on their hand, get to invest into a booming industry and generate a stream of passive, daily, income.
Unfortunately there has been some cases of scam in this industry. Companies claiming to invest their client's money into mining equipment, when they were in fact running ponzi schemes.
Serious companies, such as Genesis Mining, will provide proof that they do own large (and growing) mining facilities.
You can find footage and pictures taken inside Genesis Mining's facilities on the Internet, proving they are indeed a legit company. You shouldn't trust any company that doesn't provide such proofs.
