David Sacks Declares Crypto Fulfills PayPal Vision as Bitcoin Smashes Through $4,300

Executive Summary

Bitcoin has charged past $4,300 to a new all-time high on August 14, 2017, capping off a remarkable week that also saw Coinbase announce a $100 million Series D funding round at a $1.6 billion valuation. The cryptocurrency market as a whole is experiencing a surge of institutional interest, validated by former PayPal COO David Sacks declaring that cryptocurrencies are fulfilling PayPal’s original vision of creating a “new world currency.” With a combined market capitalization approaching $140 billion, the digital asset class is rapidly maturing from a niche experiment into a recognized component of the global financial system.

The Numbers Unpacked

Bitcoin reached $4,238 on August 14, posting a daily gain of 4.89 percent and bringing its seven-day advance to nearly 26 percent. The rally is fueled by a combination of strong Japanese demand, post-SegWit optimism, and growing institutional interest. Trading volume across major exchanges topped $97 million in 24 hours on Kraken alone, with total global spot volume exceeding $3 billion.

Ethereum, the second-largest cryptocurrency by market capitalization, is trading at $302, up 3.73 percent on the day. Its market cap stands at approximately $28 billion. Bitcoin Cash, born from the August 1 hard fork, is trading at $297, down 3.37 percent as miners and users continue to overwhelmingly favor the original Bitcoin chain. The total cryptocurrency market capitalization has swelled to approximately $137 billion, according to CoinMarketCap data.

Perhaps most striking is the performance of several altcoins. Neo has surged over 200 percent in the past seven days to reach $46.65, while OmiseGO has gained 141 percent to trade at $6.94. IOTA is up 92 percent week-over-week. These moves reflect a broad-based risk-on sentiment across the entire digital asset market, not confined to Bitcoin alone.

Historical Context

The current rally carries echoes of previous Bitcoin bull runs, but with important differences. The April 2013 surge to $260 was driven primarily by the Cyprus banking crisis and a relatively small community of early adopters. The November 2013 run to $1,200 was dominated by Chinese exchange volume, much of which later proved inflated. The 2017 rally, by contrast, is characterized by genuinely global participation, growing regulatory clarity, and the emergence of institutional infrastructure.

The successful activation of Segregated Witness on August 8 removed what had been a major overhang on the market. For over a year, the scaling debate had created uncertainty about Bitcoin’s capacity to handle growing transaction volumes. With SegWit now locked in and activated, the path is open for Lightning Network development and other layer-two scaling solutions. This technical progress has emboldened investors who previously sat on the sidelines.

The Bitcoin Cash fork on August 1, initially feared as a potentially disruptive event, has actually reinforced confidence in the original chain. The fact that Bitcoin survived the fork without significant disruption, and that the market has assigned the vast majority of value to the original chain, demonstrates the resilience of the network. The market is effectively voting with its capital, and the verdict is clear.

Expert Consensus

David Sacks, the former COO of PayPal and a member of the so-called PayPal Mafia, delivered one of the most significant endorsements of cryptocurrency to date in a CNBC interview on August 14. Sacks stated that bitcoin is fulfilling PayPal’s original vision to create “the new world currency,” revealing that PayPal had T-shirts printed in 1999 with that very mission statement. He drew a direct parallel between PayPal’s centralized attempt at building a global payment database and the decentralized approach that cryptocurrencies have taken.

“Cryptocurrencies like bitcoin are now fulfilling that original vision,” Sacks explained. “They are doing it in a decentralized way with a decentralized database called the blockchain, whereas PayPal tried to do it in a centralized way.” Sacks went further, calling the current moment the birth of “Web 3.0” and comparing it to the dot-com era in terms of both revolutionary potential and speculative excess.

The Coinbase funding round adds institutional weight to the bullish narrative. The $100 million Series D, led by IVP with participation from Spark Capital, Greylock Partners, Battery Ventures, and others, brings Coinbase’s total funding to $217 million. The company plans to use the capital to improve customer experience, serve institutional clients, and invest in Toshi, a consumer-facing Ethereum wallet app. The $1.6 billion valuation makes Coinbase the first cryptocurrency company to achieve unicorn status.

Greenwich Associates analyst Richard Johnson, writing in Fortune, argues that Coinbase’s focus on digital currencies as an enabling technology rather than just a tradeable asset positions it to have a bigger impact on mainstream adoption than derivatives exchanges like LedgerX or the CBOE’s planned bitcoin futures. The key test, Johnson notes, will be whether Coinbase can help digital currencies “cross the chasm” from early adopters to the mainstream majority.

Forward Outlook

The immediate catalyst to watch is the continued rollout of SegWit adoption. As more wallets and services implement SegWit addresses, the effective block capacity should increase, potentially alleviating the congestion that has plagued the network. This could reduce transaction fees, which have been a persistent pain point for users, from average highs of $4-5 per transaction down to $1-2.

The institutional pipeline is deepening rapidly. The CFTC’s approval of LedgerX to operate a federally regulated bitcoin options exchange, announced just days ago, opens the door for institutional hedging strategies. The CBOE’s plans for bitcoin futures, once launched, would provide another regulated on-ramp for traditional financial institutions. These developments are not speculative—they represent regulatory and market infrastructure that is actively being built.

Looking further ahead, the SegWit2x hard fork scheduled for approximately November remains the most significant risk factor. If the fork proceeds as planned and results in another chain split, it could introduce temporary uncertainty. However, the smooth handling of the Bitcoin Cash fork has given the market confidence that such events can be managed without catastrophic disruption.

The bullish case for the remainder of 2017 rests on the convergence of technical progress (SegWit, Lightning), institutional adoption (Coinbase, LedgerX, CBOE), and growing mainstream awareness. The bear case centers on regulatory risk, particularly in China and South Korea, and the possibility that current price levels reflect speculative excess rather than fundamental value. With Bitcoin now up over 300 percent year-to-date, both cases have merit. What is undeniable is that August 2017 represents a watershed moment in the maturation of cryptocurrency as an asset class.
