They literally put it in their pr's. Metatron approved investors can acquire Series B shares in blocks of various sizes starting at 1k and recently increased discounts. The first round investors will receive the highest discount. Series B shares can be redeemed through the Company, are immune to reverse splits, and will convert at 1 B share to 50,000 common shares at a 60% discount.
Usually the discounts get deep near the collapse of a ponzi scheme.
