Epic Rare and uncommon heroes are available at the My Crypto Heroes sale.
The sale will last for two weeks. Starting from [UTC] February 26th 7:00 until March 12th 6:00. At the first week only prime users will be able to buy, so users that are not subscribed to MCH prime will participate in the second week.
Meet “Takeda Shingen” “Pocahontas” and “Xu Chu”
The selling method is stock-linked Dutch auction in the crypto world. That means that the value increases every time a hero is purchased and it decreases gradually over time. The minimum price will be half the price of the highest bid and the growth rate of the price will increase (as far as 100%). Also, note that if you successfully purchase a hero you will have to wait for 1 minute to purchase the same hero again.
