Bitcoin has officially entered four-figure territory that few dared to imagine just months ago. On August 27, 2017, the world largest cryptocurrency is trading at $4,382, having surged more than 6% in the past week alone. The catalyst? The long-awaited activation of Segregated Witness (SegWit) on August 24 — a milestone that has reignited bullish sentiment across the entire digital asset ecosystem.
TL;DR
- Bitcoin hits $4,382 following SegWit activation on August 24, 2017
- Total cryptocurrency market cap approaches $148 billion
- Monero leads altcoin surge with 139% weekly gain
- Ethereum rises 16% to $348 as ICO market continues booming
- Bitcoin Cash declines 16%, signaling market consolidation around original chain
The SegWit Effect: Three Days That Changed Bitcoin
After years of heated debate, multiple scaling proposals, and the specter of a chain split, Segregated Witness finally locked in on the Bitcoin network. The upgrade, which went fully active on August 24, represents the most significant protocol change to Bitcoin since its inception. By separating signature data from transaction data, SegWit effectively increases block capacity without raising the block size — a compromise that satisfied both sides of the scaling debate, at least temporarily.
The market response has been emphatic. Bitcoin has rallied more than 6% in the week following activation, pushing through $4,400 at its peak. Trading volume has surged, with $1.54 billion in BTC changing hands in the past 24 hours alone. The total Bitcoin market capitalization now stands at an impressive $72.4 billion, cementing its position as the undisputed king of cryptocurrencies.
But SegWit significance extends beyond price action. The elimination of transaction malleability — a long-standing technical limitation — opens the door to Lightning Network development, which promises near-instant, low-cost Bitcoin transactions. It also enables more sophisticated second-layer applications, including those related to digital assets and collectibles built on top of the Bitcoin blockchain.
Altcoins Stage a Spectacular Rally
While Bitcoin grabs the headlines, the altcoin market is putting on a show of its own. Monero has been the standout performer, surging an extraordinary 139% over the past seven days to reach $130.67. The privacy-focused cryptocurrency has been buoyed by growing demand for anonymous transactions and speculation about adoption on darknet marketplaces following AlphaBay takedown in July.
Litecoin, often described as the silver to Bitcoin gold, has gained 31.5% to reach $61.16. Litecoin was one of the first major cryptocurrencies to activate SegWit earlier in 2017, and the network is now reaping the benefits of that early adoption. XRP has also shown strength, rising 28% over the week to $0.203, with its parent company Ripple continuing to forge partnerships with banks and financial institutions worldwide.
Ethereum, the second-largest cryptocurrency by market cap, has risen 16% to $347.89, with a market capitalization of $32.8 billion. The Ethereum network continues to be the platform of choice for the booming ICO market, with new token sales launching daily. Projects like Propy, a blockchain-based real estate platform, raised nearly $8 million on the first day of their crowdsale this week, underscoring the insatiable appetite for blockchain investments.
Bitcoin Cash: The Fork That Lost Its Luster
Not every cryptocurrency is sharing in the gains. Bitcoin Cash, which forked from the Bitcoin blockchain on August 1, has declined 16% over the past week to $620.90. After an initial surge that saw BCH prices briefly exceed $900, the forked currency has been steadily losing ground as miners and users gravitate back toward the original Bitcoin chain.
The declining hash rate on the Bitcoin Cash network has raised concerns about its long-term viability. While BCH proponents argue that larger blocks are essential for scaling, the market appears to be voting with its feet — and its money — in favor of the SegWit path. The Bitcoin Cash market cap now stands at $10.3 billion, a fraction of Bitcoin $72.4 billion.
What the Numbers Tell Us
The cryptocurrency market on August 27, 2017, paints a picture of a maturing ecosystem undergoing rapid expansion:
- Bitcoin: $4,382.88 (Market cap: $72.4B, 24h volume: $1.54B)
- Ethereum: $347.89 (Market cap: $32.8B, 24h volume: $633M)
- Bitcoin Cash: $620.90 (Market cap: $10.3B, declining)
- XRP: $0.203 (Market cap: $7.8B)
- Litecoin: $61.16 (Market cap: $3.2B, 24h volume: $891M)
- Monero: $130.67 (Market cap: $1.96B, weekly gain: +139%)
The total market capitalization of all cryptocurrencies now approaches $148 billion — a staggering figure that would have seemed unimaginable just one year ago when the total market cap hovered around $10 billion.
Why This Matters
The events of late August 2017 represent a watershed moment for Bitcoin and the broader cryptocurrency ecosystem. The successful activation of SegWit proves that Bitcoin can evolve through consensus rather than fragmentation. The spectacular altcoin rally demonstrates that investor interest extends far beyond Bitcoin itself. And the declining fortunes of Bitcoin Cash suggest that the market values technical sophistication over simple block size increases.
Most importantly, the infrastructure being built today — from Lightning Network on Bitcoin to the exploding ICO ecosystem on Ethereum — is creating the foundation for an entirely new financial system. The $148 billion cryptocurrency market is still tiny compared to traditional financial markets, but the velocity of growth suggests we are still in the very early stages of something transformational.
For digital asset enthusiasts, the SegWit activation carries particular significance. By enabling more complex smart contracts and second-layer protocols on Bitcoin, it opens new possibilities for token issuance, digital collectibles, and novel forms of on-chain ownership that were previously impractical. The next chapter of the digital asset revolution is being written right now — on the Bitcoin blockchain itself.

segfault_ people really forget btc was like 48 hours from a chain split. segwit was the last second compromise that held it all together
blocksize_ref_ the 2x part of NYA was what scared everyone. segwit passing felt like dodging a bullet that would have split the chain in two
segfault_ people really do forget how close we came to actual chain split. segwit wasnt just technical — it was a political miracle that kept the ecosystem from fracturing completely
48 hours from split still gives me chills. segfault_ captured the tension perfectly.
monero up 139% in a week and nobody was talking about it because all eyes were on btc. classic alt rotation signal
xmr up 139% in a week while nobody noticed is peak alt season behavior. money flowing to the most neglected corners
Olaf K. monero at 139% while btc stole the spotlight is textbook rotation. same pattern repeats every cycle, just different alts
Monero up 139% during the SegWit wars was the clearest alt-season signal of that cycle.
Priya Rao monero doing 139% while everyone was glued to the segwit vote tells you money was rotating hard into privacy coins that cycle. xmr was the degen play nobody talks about anymore
bch dropping 16% while btc pumped was the market telling roger ver what it thought of the fork. brutal
bch_down_bad that 16% drop vs btc’s surge was the market’s real referendum. roger ver’s fork narrative just didn’t hold up against the original chain’s security and network effect
monero up 139 percent in a week shows altcoins can move hard when bitcoin clears 4382 after segwit
btc at 4382 felt expensive back then. wild to think people were split between core and cash and the market just decisively picked the original chain. bch down 16% that same week was the verdict
reading this at btc 108k hits different. 4400 was the mental barrier back then and people thought we were irrational bulls
imagine paying 4382 for a whole btc. wild times
gould_chain my first whole btc was at 4200 right after this. thought i overpaid. held for 5 years and that thing paid for my house
gould_chain bought my first BTC at 4200 right after segwit too. held through 69K and never sold a single sat. diamond hands were easier when the price had 4 digits
$148 billion total crypto market cap in august 2017. we are what, 8x that now? feels like the early days in retrospect
$148B total market in 2017 feels tiny now. SegWit was the last time Bitcoin felt truly at risk of splitting.
Mateo Ruiz exactly. $148B in 2017 feels like pocket change now. segwit bought us time but scaling solutions back then seem primitive compared to today’s layer 2s
