Let's consider this question on example of the TerraMiner large project offering to investors the most transparent cooperation conditions. If you make investments in your own equipment then in case of its failure or obsolescence your money just burn down. You should make investments again. If it's about cryptoinvestments into TerraMiner, then you buy not the equipment, but the part of profitable farm capacities. Whether the equipment at the farm work or it should be replaced – the investor doesn't need to pay extra money, his rights for the equipment aren't lost, he keeps the share of property and gains income proportional to quantity of his tokens. Another advantage is that you don't need to personally conduct farm maintenance and to control its work. While cryptoinvestments make profit, you go take care about your own business. As the future is about such large-scale projects like TerraMiner, the farm investors can be sure of their income stability – unlike small miners.
