The world of digital assets continues to evolve at a rapid pace, with significant advancements across blockchain technology, institutional adoption, and global regulatory responses. This comprehensive overview captures key events from mid-September 2021 that shaped the crypto landscape — from major platforms integrating cryptocurrency features to national governments responding to decentralized finance trends.
Twitter Enables Bitcoin Tips for iOS Users
In a move signaling broader mainstream acceptance, Twitter has rolled out a Bitcoin tipping feature for iOS users through the Lightning Network. The integration allows users to send and receive small Bitcoin payments as tips, enhancing creator monetization on the platform.
This functionality relies entirely on third-party services, with Strike — a Bitcoin Lightning wallet application — serving as the primary payment processor. By embedding Strike’s infrastructure, Twitter enables seamless peer-to-peer transactions without handling funds directly. This development underscores growing interest in using Bitcoin not just as a store of value but as a medium for microtransactions in social ecosystems.

Robinhood Tests In-App Crypto Wallet Functionality
Robinhood, the popular stock and cryptocurrency trading app, is testing an integrated crypto wallet within its mobile application. Previously, users could only trade cryptocurrencies on the platform but couldn’t transfer them externally. With this new feature, customers will gain full control over their digital assets, enabling transfers to and from external wallets.
The introduction of self-custody options marks a strategic shift for Robinhood, aligning it more closely with traditional crypto exchanges. It also responds to user demand for greater flexibility and ownership — critical factors in promoting long-term adoption of digital currencies.
Why Wallet Integration Matters
- User empowerment: Gives traders direct access to their private keys and assets.
- Interoperability: Facilitates participation in decentralized finance (DeFi) and non-fungible token (NFT) markets.
- Market competitiveness: Positions Robinhood alongside platforms like Coinbase and Binance in offering comprehensive crypto services.
AMC to Accept Ethereum, Litecoin, and Bitcoin Cash
AMC Entertainment, one of the largest movie theater chains in the U.S., announced plans to accept Ethereum (ETH), Litecoin (LTC), and Bitcoin Cash (BCH) for online ticket purchases and concession payments by the end of 2021. CEO Adam Aron confirmed the expansion of its crypto payment system, which initially included only Bitcoin.
This multi-cryptocurrency approach reflects increasing corporate confidence in blockchain-based payment systems. By supporting multiple leading altcoins, AMC is catering to a wider digital asset holder base while reinforcing its image as a forward-thinking brand embracing financial innovation.
Vitalik Buterin Named Among Time’s 100 Most Influential People
Vitalik Buterin, co-founder of Ethereum, was recognized by Time magazine as one of the 100 most influential people of 2021. The acknowledgment highlights his pivotal role in advancing smart contract technology and decentralized applications (dApps). Alongside figures like Elon Musk — also known for his support of Dogecoin — Buterin represents the intellectual foundation of the modern blockchain movement.
Ethereum's ongoing evolution, including the transition to Proof-of-Stake and Layer-2 scaling solutions, continues to shape the future of Web3 and decentralized finance.
Ethereum’s BTC-Backed Tokens Surpass 280,000 Milestone
A major milestone was reached as the total supply of Bitcoin-anchored tokens on the Ethereum blockchain exceeded 280,000 BTC. At current valuations, this represents over $12.6 billion in locked value. These wrapped assets, such as WBTC (Wrapped Bitcoin), allow Bitcoin holders to participate in Ethereum’s DeFi ecosystem.
The growth reflects strong demand for cross-chain liquidity and demonstrates how interoperability is becoming central to decentralized finance. As more assets become available across blockchains, users gain access to yield farming, lending, and synthetic derivatives markets powered by Ethereum’s smart contracts.
Greenidge Generation Set to List on Nasdaq
Greenidge Generation Holdings Inc., a U.S.-based Bitcoin mining company, completed its merger with Support.com and began trading on the Nasdaq stock exchange. The listing marks another step toward institutional legitimacy for cryptocurrency mining operations.
As environmental concerns around proof-of-work mining persist, Greenidge has emphasized its use of previously retired power plants and carbon offset initiatives. Its public market entry may encourage further investment in regulated, transparent mining ventures.
Alipay Launches ‘I Am Not the Fat Tiger’ NFT Series
In China, where cryptocurrency trading faces strict regulations, Alipay launched a limited-edition NFT series titled I Am Not the Fat Tiger. The collection features two designs — Tiger Climbing Mountain and Tiger Descending Mountain — with 8,000 copies released per session across four time slots.
While these tokens are built on blockchain technology, they are not tradable or transferable due to local compliance requirements. This model reflects a state-sanctioned approach to digital collectibles — distinct from open-market NFTs — focusing on cultural expression rather than speculation.
Additionally, Alipay revealed plans to launch a digital torch for the Hangzhou Asian Games, further showcasing blockchain’s potential in sports and national events.
Turkey’s President Declares War on Cryptocurrencies
In contrast, Turkish President Recep Tayyip Erdogan declared that Turkey is “at war” with cryptocurrencies. This stance follows the central bank’s April 2021 ban on using digital assets for payments, citing financial stability and consumer protection concerns.
Despite high inflation driving domestic interest in alternative stores of value, the government remains cautious about losing monetary control. The crackdown illustrates the tension between decentralized finance and centralized economic policy — a challenge faced by many emerging economies.
Federal Reserve Signals Tapering Plans
On the macroeconomic front, Federal Reserve Chair Jerome Powell indicated that the central bank will begin tapering its asset purchase program later in the year. While not directly targeting cryptocurrencies, monetary tightening can influence investor behavior in risk-on assets like Bitcoin and Ethereum.
Powell noted that inflation pressures are likely to persist longer than expected but reiterated that policy adjustments would be gradual and data-dependent. Markets continue to assess how evolving monetary policy may affect capital flows into digital assets.
