Bitcoin has surged past the $2,800 mark for the first time in weeks, trading at approximately $2,875 on July 31, 2017, as the cryptocurrency community celebrates a critical milestone in the network’s evolution. The Segregated Witness (SegWit) upgrade, one of the most anticipated and controversial changes in Bitcoin’s history, is now firmly in its lock-in period following the successful activation of BIP 91 on July 21.
TL;DR
- Bitcoin trades at $2,875, up over 50% from mid-July lows near $1,835
- SegWit lock-in period underway after BIP 91 activated on July 21 at block 477,120
- Full SegWit activation expected around August 24 at block 481,824
- Bitcoin Cash hard fork scheduled for August 1 at block 478,559
- Market cap for Bitcoin stands at approximately $47.4 billion
SegWit Lock-In: A Turning Point
The road to SegWit has been anything but smooth. For months, the Bitcoin community found itself divided between two competing visions for scaling the network. On one side stood proponents of Segregated Witness, a technical upgrade that would effectively increase block capacity without changing the base block size limit, while also fixing the long-standing transaction malleability problem. On the other, a coalition of miners and developers favored a straightforward block size increase.
The breakthrough came on July 21, when miners successfully activated BIP 91, which locked in SegWit at block 477,120. According to data from the network, miner signaling for SegWit has been trending toward 100%, with the upgrade on track for full activation around August 24 at block height 481,824. The speed of the lock-in caught many observers by surprise, as it effectively ended months of uncertainty that had weighed on the market.
Price Action Reflects Growing Confidence
Bitcoin’s price tells the story of the market’s response. On July 14, BTC was trading at approximately $1,835. By July 31, it had rallied to $2,875 — a gain of over 56% in just over two weeks. The surge represents one of the most dramatic two-week price movements in Bitcoin’s 2017 rally, which has seen the cryptocurrency rise from under $1,000 at the start of the year.
The broader cryptocurrency market has also benefited. The total market capitalization of all cryptocurrencies has grown significantly, with Bitcoin alone commanding a market cap of roughly $47.4 billion. Litecoin, which activated SegWit earlier in 2017, has also seen gains, trading at approximately $43 with a 6.59% gain over the past 24 hours.
The Bitcoin Cash Factor
Not everyone in the Bitcoin community is celebrating, however. A group of miners, led in part by hardware manufacturer Bitmain and mining pool ViaBTC, has pushed forward with plans for a hard fork scheduled for August 1. The resulting cryptocurrency, dubbed Bitcoin Cash (BCH), will feature 8 MB blocks — a direct challenge to Bitcoin’s current 1 MB limit.
The fork, set to occur at block 478,559, will create a new blockchain that shares Bitcoin’s transaction history up to that point. This means anyone holding Bitcoin at the time of the fork will receive an equivalent amount of Bitcoin Cash. The cryptocurrency community is watching closely, as the fork represents the first major chain split in Bitcoin’s history and could set a precedent for future governance disputes.
What SegWit Means for Bitcoin’s Future
Beyond the immediate price impact, SegWit’s activation carries significant technical implications. By separating signature data from transaction data, SegWit effectively increases the amount of transaction data that can fit in each block without a hard fork. More importantly, it fixes the transaction malleability problem, which has been a key obstacle for second-layer solutions like the Lightning Network.
The Lightning Network promises to enable near-instant, low-cost transactions by creating payment channels that operate off the main blockchain. With SegWit activation now certain, developers can begin building this infrastructure in earnest, potentially addressing Bitcoin’s long-standing scalability challenges without compromising the network’s decentralization.
Why This Matters
The events of late July 2017 represent a watershed moment for Bitcoin. The successful lock-in of SegWit demonstrates that the network can navigate deeply contentious governance disputes and emerge with a path forward. At the same time, the upcoming Bitcoin Cash fork highlights the ongoing tensions between different visions for cryptocurrency scaling. For investors and users alike, the next few weeks will be critical in determining how these competing approaches coexist and whether Bitcoin’s remarkable 2017 rally has further room to run.

50% rally in two weeks off the SegWit news. that was the moment the scaling war felt resolved
Boris N the 50% rally from 1835 felt like relief more than euphoria. we were all terrified BIP 91 would fail and btc would split into 3 chains
the rally was real but Bitcoin Cash forking off on Aug 1 created months more uncertainty. SegWit locked in but the community was still fractured
Karl W. BCH forking off was actually a relief valve. it let the big blockers leave without dragging BTC into a contentious hard fork
split_accept_ the 95% threshold felt safe until some pools started signaling support while mining empty blocks against the spirit of the agreement
split_accept_ the BCH fork as a relief valve is a good take. big blockers got their chain and BTC got its upgrade. everybody won except the people who sold before Aug 1
btc at 2875 after a 50 percent run from 1835 in two weeks. that segwit lockin rally was the original gamma squeeze
bip91_witness calling it a gamma squeeze is exactly right. dealers were short calls into the lockin and had to delta hedge into thin summer liquidity
BTC at 2875 with a 47B mcap felt astronomical at the time. 4 months later it was 20K. the post-segwit rally was the most violent run in btc history
witness_data_ the BCH fork 2 days after segwit lock-in was the real chaos. everyone thought BTC was splitting 3 ways. surviving that week made the december run feel earned
remember being glued to block height counters waiting for BIP 91 signaling. felt like watching an election
carbuncle_ block height counters on twitter refreshing every 30 seconds. peak crypto stress. BIP 91 felt like it could go either way until the last 48 hours
the signaling period was more stressful than any halving since. felt like the entire future of btc hung on hitting that 80% threshold
block_header_ the 80 pct signaling period was more stressful than any halving. checking block height counters every 10 minutes for weeks was genuinely unhinged
genesis_block_ checking block height counters every 10 minutes for weeks was genuinely unhinged behavior. but we had reason. if BIP 91 failed BTC was splitting into 3 chains and nobody knew which one would keep the ticker
BCH forking off 2 days after BIP 91 locked in was the relief valve. big blockers got their chain, BTC got SegWit. everyone won except people who panic sold on July 27
BIP 91 signaling at block 477120 was the most stressful block watch ever. refreshing block explorers every 30 seconds for a week straight
$2,875 felt expensive back then. funny how that works
every cycle has its “feels expensive” moment. $2800, $20k, $69k. the pattern never changes
BIP 91 activation at block 477120 was the most tense moment in BTC history. miners signaling yes while secretly mining BCH the whole time
segwit_veteran_ miners signaling yes while mining BCH secretly was the most two-faced thing. slush pool was the only honest major pool during that whole saga
segwit_veteran_ miners signaling yes for BIP 91 while secretly mining BCH the whole time. the double game during that period was the most dishonest thing Ive seen in crypto and I include FTX in that
block 477120 for BIP 91 then 478559 for BCH two days later. august 2017 was the most stressful month in btc history and i include the ftx crash
BTC at $2,875 with a $47B market cap. now its 100k plus with a 2T cap. the block size war was the best thing that ever happened to this network
BTC at 2875 feeling expensive and a 47B market cap. august 2017 into december to 20k was the craziest 4 month run ever. segwit unlocking lightning was the fundamental shift
