Stay Creative > Keep Posting > SteemOn
Thank you for words. I am trying to promote Steemit to every person who will listen to me. As a teacher, my students are very inquisitive about what platform I am using. When I explain it to them, they are first suscipious but then excited about the possibilities.
It is a new way of thinking. To hold value in people that makes a platform work. Who has ever thought of that and made it successful? There are no ads because the value somes from the people.Decentralized/blockchain/free speech/transparent and on and on it goes. Steemit is going opposite of the world's ways. This is going to be bigger than bit-coin.
You came to the right place because we're about to have it all
