Why gwadar will grow into bigger settlement than murree?

Murree is an older settlement than Gawadar because British bought Murree from the elders in 1853 and settled there where as Gawadar was bought by Prince karim Agha Khan on 8th september 1958 from Oman and he gifted it to Pakistan...So Murree is developed from 150 years where as Gawadar has now started to develop..
