As soon as we can be active consumers within the STEEM economy, being able to purchase household items, food, services, etc. directly with steem in a marketplace. I believe that is what @dstors is about. A wholesaler website who attaches itself to the blockchain is ideal. A digital costco would be nice. When that happens, game over FIAT system\s. If people could use debit cards to purchase the services/items in steem using a USD to STEEM conversion app would be and ideal step torwards the direction of mass adoption. Smart call on taking a break on steem witnessing, time to hodl and invest!
