The user interface was easy to learn for new users as well as existing ones who are familiarized in other exchanges like eBay or Amazon. I think that this platform can be improved by having more options about how much you want your bid price to go up or down when someone bids against yours so it's not always one rate per second. This allows me to have my prices set correctly depending if there will be competition from others bidding at similar times than mine (in case they're willing to pay higher rates). Also we get better returns since our ads run longer before being canceled due to lack of demand.
