Is this a cryptocurrency version of Ebay? What is the size of the target market for project like this?
No, it's not cryptocurrency version of Ebay. First, because we sell for fiat money and usual marketplace users do not deal with crypto. Second, because at Ebay as far as we know is usual auction where buyers increase the price and the highest price wins. But WINBIX uses modified model of reversed auction. The prices decrease from the highest (start price) until the first buyer stops the process (buys). Of course, there are limitations - the lowest price, auction duration limitations etc. And, that is important, the process of price decrease is not linear. The start and the lowest prices change from auction to auction, auction duration differs. All of these parameters are managed by special algorithm. Please, take a minute to explore

As to the target market size - it's not lower than Ebay's 😉
