You can still earn from your blog if it's not hosted. But your earnings is limited if you're using a free blogging site under a subdomain. You won't earn from AdSense, unless you want to use it to promote your digital skills, or items, affiliate marketing, and from low paying Ads etc.Thanks for your advice @Sincerem, I thought I read that you could generate profits without having a paid blog, with the free one you could also make profits. I must remember and reread the information, because it does not match what you leave written.
