The cryptocurrency world experienced a turbulent Independence Day on July 4, 2017, as one of the most bullish Wall Street forecasts clashed with a major security breach at South Korea’s largest crypto exchange. The juxtaposition of institutional optimism and real-world vulnerability perfectly captured the contradictions defining Bitcoin’s maturation.
TL;DR
- Goldman Sachs analyst Sheba Jafari predicted Bitcoin could reach $3,915, calling it “just a matter of time”
- South Korea’s Bithumb exchange suffered a hack compromising personal data of roughly 3% of its user base
- Bitcoin traded at approximately $2,601, down from its June 11 all-time high of $3,025
- The network hashrate surged 30% in a single 24-hour period, signaling growing miner confidence
- Segwit2x scaling proposal garnered support from approximately 90% of miners
Goldman Sachs Goes Long on Bitcoin
In a report that sent ripples through traditional finance, Goldman Sachs technical analyst Sheba Jafari laid out an ambitious case for Bitcoin’s continued ascent. According to Jafari’s Elliott Wave analysis, the cryptocurrency was undergoing a necessary correction that could see prices dip to as low as $1,875 before staging a dramatic recovery.
“From current levels, this has a minimum target that goes to $3,212,” Jafari wrote in the note. “It’s just a matter of time.”
The analyst’s upper-bound projection placed Bitcoin at $3,915, which would have represented a fresh all-time high at the time. The prediction carried particular weight given Goldman Sachs’ evolving stance on cryptocurrency. The firm had previously described Bitcoin as the “ideal vehicle” for public transactions and forecasted wide-scale blockchain adoption within five to ten years.
Bitcoin had been trading in a holding pattern around the $2,500 to $2,800 range following its June 11 peak of $3,025.47. The consolidation reflected growing uncertainty over which scaling path the network would adopt, with the Segwit2x proposal drawing both significant miner support and heated criticism from Bitcoin Core developers.
Bithumb Breach Exposes Industry’s Security Gaps
While Wall Street analysts painted an optimistic future, the present delivered a stark reminder of crypto’s fragility. Bithumb, South Korea’s highest-volume cryptocurrency exchange, confirmed that hackers had infiltrated employee computers and made off with what local media described as “tens of millions of won,” with some reports suggesting the figure could reach into the billions of won.
The attack was particularly damaging to user trust. According to reporting by Kyunghyang Shinmun, unidentified victims stated that their accounts had been hacked, mobile phone numbers leaked, and funds withdrawn without authorization. The exchange acknowledged that personal information — including phone numbers and email addresses — of approximately 3% of its total client base had been compromised.
Bithumb’s initial response drew criticism. The exchange offered affected users a fixed compensation of 100,000 won, roughly $86.85 at the time — a figure that struck many as woefully inadequate given the severity of the breach. The exchange stated it had immediately contacted the Korean Internet and Security Agency (KISA) and was conducting an investigation.
The incident wasn’t isolated. Just days earlier, EthereumClassicWallet had lost approximately $300,000 worth of ETC after a social engineering attack on its domain host. Meanwhile, Coinbase continued to struggle with technical issues that left customers reporting missing transactions and unresponsive support.
Hashrate Surge Signals Underlying Strength
Beneath the headline chaos, Bitcoin’s fundamentals showed remarkable resilience. The network’s hashrate registered a staggering 30% increase in a single 24-hour period ending July 3, a metric that analysts interpreted as a strong confirmation of the underlying bullish trend.
The mining surge was not confined to any single geography. Reports from Russia indicated GPU shortages driven by a veritable mining gold rush, while demand from Japan, India, and Venezuela continued to push prices higher on global exchanges. In South Korea specifically, Bitcoin regularly commanded a significant premium over prevailing global rates — a phenomenon known as the “kimchi premium” that would become increasingly relevant in the months ahead.
Scaling Debate Looms Over Price Action
The sideways price action around July 4 reflected more than just post-hack jitters. The Bitcoin community was locked in an increasingly contentious debate over the Segwit2x scaling proposal, which had been forged at a meeting of industry participants in New York earlier that spring. While approximately 90% of miners signaled support for the compromise, prominent Bitcoin Core developers and community members voiced concerns about the proposal’s second phase, which called for a 2-megabyte block size increase.
Critics argued that Segwit2x’s hard fork component represented a dangerous precedent, while supporters maintained that the agreement represented the best chance for avoiding a chain split. The uncertainty kept many traders on the sidelines, creating the very consolidation pattern that Jafari’s analysis identified as a launchpad for the next major move.
Why This Matters
July 4, 2017 represented a microcosm of Bitcoin’s coming-of-age story. Goldman Sachs’ public bullishness signaled that institutional finance was no longer dismissing cryptocurrency as a passing fad — it was actively charting its trajectory. Simultaneously, the Bithumb hack demonstrated that the infrastructure supporting this nascent asset class remained dangerously immature.
The tension between these two forces — institutional legitimization and operational vulnerability — would define Bitcoin’s narrative throughout the remainder of 2017. Those who navigated both sides of this equation correctly were positioned for extraordinary gains as Bitcoin ultimately surged past $4,000 in August and continued climbing toward its eventual December peak near $20,000.

Jafari called $3,915 from $2,601 using Elliott Wave analysis. BTC did eventually reach that level but not before correcting to $1,800. timing was brutal
Bithumb losing personal data of 3% of users in 2017 was the first major Korean exchange breach. it triggered KYC reforms that took years to implement properly
Minseo P. 3% sounds small but Bithumb had millions of users. that data breach affected more people than most CEX hacks that came after
hashrate jumping 30% in 24 hours while miners signaled segwit2x at 90%. they were hedging both sides. miner signaling was game theory not conviction
Jafari called 3915 from 2600 and BTC topped at 2760 before correcting. directionally right but anyone who bought at her target was underwater for weeks
3% of Bithumb users back then was basically everyone who had an account. KR exchanges had zero compartmentalization between hot and cold wallets in 2017
sheba jafari calling 3915 from 2600 was one of the best wall street calls on btc. nailed it
jafari called 3915 and BTC topped at 2760 before correcting. directionally right but timing was brutal for anyone who aped in at her target
Jafari used Elliott Wave which is basically astrology for charts. BTC did pump to ~3900s eventually but calling it from 2600 was a coin flip
Bithumb hack and Goldman bull call on the same day. That is crypto in a nutshell lol
bithumb hack affecting 3% of users barely moved price because korean volume was already shifting to competitors. the hack accelerated KYC across all KR exchanges
3% of bithumb users affected sounds small until you realize that was hundreds of thousands of people. korean exchanges were the wild west back then
MinJae K. 3% of Bithumb users was still hundreds of thousands of people. korean exchanges in 2017 had zero KYC and even less security
Real-time monitoring tools are getting better at catching exploits early
network hashrate surging 30% in a single day in 2017. miners saw the writing on the wall before anyone else
segwit2x at 90% miner support and people still doubted it would activate. the block size wars were brutal
Real-time monitoring tools are getting better at catching exploits early
Goldman calling for 3915 when BTC was at 2601 and then making the bear case publicly for years after. classic bank behavior
hashrate_og_ Goldman calling 3915 publicly while their trading desk was building crypto exposure privately. the two-faced strategy is their whole business model
Sigrun H. Goldman calling 3915 publicly while building crypto exposure privately should surprise nobody. every Wall Street bank plays both sides
3% of users compromised at Bithumb and the exchange barely flinched. Korean exchanges in 2017 had zero security standards
bithumb_survivor 3% of users compromised and Bithumb kept operating like nothing happened. korean exchanges in 2017 had zero accountability until regulators stepped in years later
bithumb_survivor Korean exchanges in 2017 had zero security. Bithumb stored everything in hot wallets and compartmentalization was nonexistent. 3% of users was thousands of people
Goldman publicly calling 3915 while their prop desk was accumulating. the two faced strategy is literally their business model
Bithumb losing personal data of 3 percent of users and barely flinching. Korean exchanges in 2017 had zero security standards. wild west era
