Are you trying to ask that how can someone swap
steempower from another steemit account to another??if that is what you are trying to say then
the steempower cannot actually be directly
transferred to you but the person can delegate steempower from one account to the other but
the account that received th delegated steempower cannot perform powerdown on the
received delegated steempower unlike a normal steempower which you earned or have through
powering up,i think that is the huge difference
between a delgated steempower and a steempower you earned or got through powering
up..but of course a delgated steempower can still
be used for upvotes and make the steem economy better..:
