  There is a special class of so-called block-scalable initial states of the
sender whose transfer to the receiver through the spin chain results in
multiplying {their} MQ-coherence matrices by scalar factors (block-scaled
receiver's states). We study the entanglement in block-scalable and
block-scaled states and show that, generically, the entanglement in block
scaled states is less than the entanglement in the corresponding block-scalable
states, although the balance between these entanglements depends on particular
values of parameters characterizing these states. Using the perturbations of
the sender's block-scalable initial states we show that generically the
entanglement in the block-scalable states is bigger, while the entanglement in
the block-scaled states is less than the entanglements in the appropriate
states from their neighborhoods. A short chain of 6 and a long chain of 42
spin-1/2 particles are considered as examples.}
