The delegation is basically usufruct, it may have some technical problems that do not help the price of the Steem rise, but basically it is a reasonable way to put your capital into operation without resorting to theft risks. There are people who invested their money in Steem Power and then leave, while delegating a little, it is likely that without the delegation that Steem did not come to Steemit and to be held passively, but in an exchange available instantly to speculate, something that in the long term it would be worse. Or maybe I'm just raving.
