Due to the growing interest in electronic gift cards, G2A, Eneba, and others have created marketplaces that bring sellers and buyers under a platform. Growth expectation for the eGift cards business is through the roof: a turnover of $698.2 billion is expected worldwide in 2024 \[1]. Equally, the gaming industry is evolving, valued at $198.40 billion in 2021, and expected to reach $339.95 billion in 2027 at a CAGR of 8.94% \[2]. Game distribution is also growing, encompassing new sectors, such as cryptocurrency. At its all-time high, Crypto had a market capitalization of $3 trillion \[3]. The industry's payment, security, and economic benefits have developed e-commerce. In addition, technological advancement is propelling growth and improving game creation and distribution. GameGuru aims to be the leading user-centered crypto marketplace for eGift cards and digital gaming products. Traditional online marketplaces offer overpriced products, fraudulently obtained game keys, and, in most cases, none-instant delivery due to the high risk of payment reversals. GameGuru, by relying on its GGT token (BEP-20) as the only payment method, will provide lower prices, zero-risk products, and instant goods delivery guaranteed through crypto transactions’ irreversibility and API integration with vetted suppliers. --- # Agent Instructions This documentation is published with GitBook.
