Generally, if a person invests on any property or share they could not get access to the entire amount of money they are spending for it. To be the possessor of a property or any shares, either they have to complete the prolonged legal process by spending more funds for it otherwise they have to invest some money as an initial deposit. So for those expends the investor could not gain profit, but if the person invests their money on bitcoins the person could get the ownership for the entire fund they have invested to own a bitcoin and more profits than the other kind of investments. Also to gain more profits the person has to invest more frequently but to gain profits through the bitcoin network the person doesn’t want to invest more for the bitcoin account or to buy the bitcoins again. Because there are simpler ways are available to earn free bitcoins. So utilizing those ways without investing more the bitcoin user can gain more free bitcoins.
The bitcoins value is the same at all over the world, so the crypto currencies earned through other ways without purchasing from the other user also have the same value in the distributed bitcoin network. So by earning the free bitcoins also the person can gain profit as yielded by investing in the new bitcoins.
Not all the people could gain profits by investing in the properties, sometime the property value may reduce based on the demand and location therefore it won’t offer the profit as they expected. But to invest in the bitcoin account the person doesn’t have to worry about their location, because the value of the bitcoin is the same for all the bitcoins users present at different places of the world. Similarly, the free bitcoins yielded through different ways of earning also have the same value and offer more profit for the users.
