Blockchain Gaming Thrives Through Crypto Winter: CryptoKitties, MyCryptoHeroes Lead NFT Transaction Volume

The world of blockchain-based digital collectibles is quietly building momentum in February 2019, even as the broader cryptocurrency market recovers from a punishing bear market. While Bitcoin and Ethereum dominate headlines with their price surges, a dedicated community of gamers, artists, and developers is laying the groundwork for what would eventually become a multi-billion dollar non-fungible token (NFT) ecosystem—and the seeds of that growth are visible right now.

TL;DR

• Blockchain gaming and digital collectibles maintained active user bases through the 2018-2019 crypto winter
• MyCryptoHeroes, CryptoKitties, HyperDragons, Gods Unchained, and Axie Infinity led transaction volume in February 2019
• ERC-721 token standard continued gaining traction as the foundation for unique digital assets
• Enjin released its SDK protocol, aiming to bring NFT functionality to mainstream game developers
• Ethereum’s 11% price surge to $146 improved the economics of NFT creation and trading

The CryptoKitties Effect: Still Breathing, Still Breeding

It is easy to forget that CryptoKitties, the digital cat-collecting game that famously clogged the Ethereum network in late 2017, was still one of the most active blockchain applications well into 2019. By the first week of February, CryptoKitties remained among the top five blockchain games by transaction volume, alongside MyCryptoHeroes, HyperDragons, Gods Unchained, and Axie Infinity.

The persistence of these platforms through the depths of the crypto bear market is notable. While speculative traders abandoned the market in droves during 2018’s precipitous decline—with Bitcoin falling from nearly $20,000 to below $3,500—the core communities around blockchain gaming held steady. Players who had invested time and money into their digital collections had little incentive to leave, creating a sticky user base that continued generating on-chain activity even when cryptocurrency prices were at their bleakest.

On February 18, 2019, Ethereum was trading at approximately $146 according to CoinMarketCap, up 9.33% over 24 hours and an impressive 20.73% over seven days. Bitcoin stood at $3,915.71. The market-wide recovery was lifting spirits across the crypto landscape, but for NFT enthusiasts, the rally had a more practical implication: it made creating, trading, and interacting with digital collectibles economically viable again.

MyCryptoHeroes Leads the Pack

Of all the blockchain games active in early 2019, MyCryptoHeroes—a Japanese role-playing game built on Ethereum—was consistently leading transaction volume rankings. The game allows players to collect historical heroes as NFTs, level them up through battles, and trade them on open marketplaces. Its success demonstrated that blockchain gaming could find product-market fit beyond the novelty of collectible cats.

What made MyCryptoHeroes different from earlier blockchain games was its emphasis on actual gameplay rather than pure speculation. Players were motivated by progression systems, competitive battles, and social features—not just the hope of flipping a digital asset for profit. This distinction would prove to be an important template for the next generation of blockchain games.

Gods Unchained and Axie Infinity: Early Glimpses of the Future

Two other names on the February 2019 leaderboard would go on to become defining projects of the NFT era. Gods Unchained, a trading card game backed by prominent investors, was building what it hoped would be the “Hearthstone of blockchain”—a competitive card game where players truly owned their cards as NFTs. Axie Infinity, the Pokemon-inspired battle game, was still in its early stages but already showing the kind of engaged community that would later make it a phenomenon.

In February 2019, both projects were relatively small by mainstream gaming standards, but their presence in the top-five blockchain games by transaction volume signaled genuine user engagement. Gods Unchained was running early access tournaments, while Axie Infinity was refining its battle mechanics and land system. Neither project could have predicted the explosion of interest that would come in 2020 and 2021, but the foundations were being laid in real time.

The ERC-721 Standard: Building the Infrastructure

Beneath the surface of these games, a technical revolution was underway. The ERC-721 token standard, which defines the interface for non-fungible tokens on Ethereum, was gaining broader adoption across the developer community. Unlike ERC-20 tokens, which are interchangeable (one DAI equals one DAI), ERC-721 tokens are unique by design—each token has a distinct identifier and can carry unique metadata.

This technical distinction is what makes digital collectibles possible. When a player breeds a new CryptoKitty, the resulting NFT is one-of-a-kind: it has unique genetic traits, a specific visual appearance, and a provable ownership history recorded on the Ethereum blockchain. No two are alike, and ownership cannot be disputed because it is verified by the network’s consensus mechanism.

In February 2019, Enjin—a blockchain gaming platform—released its SDK protocol, aiming to make it easier for mainstream game developers to integrate NFT functionality into their games. The Enjin ecosystem allowed developers to create, manage, and distribute blockchain-based items without needing deep expertise in smart contract development. This was a significant step toward lowering the barrier to entry for NFT adoption in the gaming industry.

HyperDragons and the Chinese Blockchain Gaming Scene

HyperDragons, another top-five blockchain game in February 2019, highlighted the growing importance of the Chinese market in blockchain gaming. The game allowed players to collect, breed, and battle dragons as NFTs, and it had cultivated a passionate community of players primarily in East Asia. Its presence on the leaderboard demonstrated that the appetite for blockchain-based collectibles was global, not limited to Western markets.

The Chinese blockchain gaming scene in early 2019 was particularly active because it operated in a somewhat gray regulatory area—game items were not classified as securities, which allowed platforms to innovate without the compliance burdens that token issuers faced. This regulatory ambiguity would eventually be clarified, but in February 2019, it provided a fertile environment for experimentation.

Market Recovery and the NFT Economy

The broader cryptocurrency market’s recovery on February 18 provided a tailwind for the NFT economy. When Ethereum trades higher, the gas costs (transaction fees) required to mint, transfer, and trade NFTs become more manageable relative to the value of the assets being exchanged. On this day, the total cryptocurrency market cap was approximately $120 billion, with Bitcoin holding a dominant position at $68.7 billion.

EOS, which was also home to some blockchain gaming projects, surged 20.56% to $3.46—the day’s biggest gainer among major coins. Litecoin hit a monthly high near $48.04, and Bitcoin Cash climbed to $144.41. The green across the board suggested that the worst of the crypto winter might be over, creating a more favorable environment for all blockchain-based activities, including digital collectible creation and trading.

The Road Ahead for Digital Collectibles

While no one in February 2019 could have predicted that NFTs would eventually generate billions of dollars in sales and capture mainstream cultural attention, the signs were there for those willing to look. The persistence of active gaming communities through the bear market, the maturation of the ERC-721 standard, and the release of developer tools like Enjin’s SDK all pointed toward a growing ecosystem.

The digital collectibles space in early 2019 was reminiscent of the early days of mobile gaming before smartphones went mainstream—the technology worked, the community was engaged, and the potential was enormous, but the broader public had not yet taken notice. That would change soon enough.

Why This Matters

February 18, 2019 captures a pivotal moment in the NFT timeline: the space between CryptoKitties’ 2017 hype and the 2020-2021 explosion. The blockchain games that were actively generating transaction volume during the depths of the bear market—MyCryptoHeroes, Gods Unchained, Axie Infinity—would become foundational projects in the NFT ecosystem. Their survival through crypto’s darkest period proved that digital ownership had genuine value beyond speculation. For investors and creators watching this space, the lesson is clear: the projects that build through the bear market are often the ones that define the next bull run.
