that were wordpress sites, except sharespark that was forum, they upload files in different file hosting sites like bdupload/mega.nz, movies were from torrent sites and torrent converted to direct links and uploaded to filehosting sites,
as you belong to south asia, i think better to open a "Retail Shop" for house hold product like "flour, salt, chillie, cooking oil, eggs, soup and etc" or Open a "General Store" for ladies items like "Whitening Creams, hair Oil, Shampo, Soup, lades under garments like bra, underware, body spray/deodrent, perfume and etc"
This will give you something atleast and you can open these retail shop or general store with low or high budget...
You can use seedbox for downloading movies for entertainment, but no income for south asian countries, as sites will disappear after long fight for income..
and i cannot tell how many movies you can stre on 10gb disk, but 300mb size movies, i can say may be few hundreds..
