next_posts_link , previous_posts_link used inside loop getting next or previous single post link.

you have use paginate_links function instead of next_posts_link

e.g.

   echo paginate_links( array(       'format' => '?paged=%#%',       'current' => max( 1, get_query_var('paged') ),       'total' => $loop->max_num_pages,       'prev_text' => '« previous',       'next_text' => 'more »',    ) );
