Ok understood. Thanks for upvoting my post! I don't quite understand why acifit from mobile doesn't post the pictures. Anyway I'm impressed by the environment of steem, it's like a virtual world in which everything is connected, in fact, as far I understood you can earn steem by posting a vid, then you can buy a card in steemonsters, you can sell card to buy steempower, you can earn by reviewing a restaurant... Such an universe of opportunity!
