The Contenders
On May 12, 2018, the altcoin landscape featured two prominent players experiencing divergent paths: Bitcoin Cash (BCH) trading at $1,472.40 and Ethereum (ETH) at $686.05. While both cryptocurrencies were reacting to the broader market turmoil caused by the Upbit investigation and regulatory uncertainty, their technical foundations and community support were driving fundamentally different narratives. Bitcoin Cash, positioned as “Bitcoin but better,” and Ethereum, the pioneer of smart contracts, were locked in their ongoing philosophical debate about the future of digital currency.
Tech Stack Showdown
Bitcoin Cash emerged from a hard fork focused on increasing block sizes and improving transaction throughput, boasting larger blocks (up to 32MB) compared to Bitcoin’s 1MB limit. This design philosophy prioritized utility as digital cash, with faster confirmations and lower fees. Meanwhile, Ethereum’s strength lay in its revolutionary smart contract platform, enabling decentralized applications, DeFi protocols, and tokenization capabilities. While BCH was optimized for simple transactions, Ethereum’s Turing-complete programming language opened endless possibilities for complex financial instruments and automated agreements.
Community & Ecosystem
The community divide between Bitcoin Cash and Ethereum supporters represented one of the most significant schisms in crypto history. BCH followers emphasized peer-to-peer electronic cash transactions and argued for Bitcoin’s original vision of a payments system. Ethereum supporters, meanwhile, championed the concept of a world computer where programmable money could enable new economic models. The ecosystem reflected these differences: BCH had strong merchant adoption and simpler wallet implementations, while Ethereum dominated developer activity, with over 200,000 GitHub repositories and countless dApps being built on its platform.
Adoption Metrics
Despite the market volatility, May 12, 2018 revealed contrasting adoption patterns. Bitcoin Cash showed strong merchant acceptance with over 2,600 businesses accepting BCH payments, primarily through platforms like BitPay and CoinGate. Ethereum, while less used for direct transactions, experienced massive growth in its DeFi ecosystem, with total value locked in smart contracts reaching unprecedented levels. The network processed significantly more transactions than BCH, though at higher costs during peak times. Market capitalization data showed Bitcoin maintaining its dominance at $144.84B, while BCH and ETH held significant portions at $25.21B and $68.19B respectively.
The Final Verdict
The events of May 12, 2018 underscored that both Bitcoin Cash and Ethereum had valid use cases but served different markets. BCH succeeded as digital cash for everyday transactions, while Ethereum excelled as a platform for financial innovation. The regulatory scrutiny affecting both cryptocurrencies highlighted the industry’s growing pains but also its increasing legitimacy. As markets reacted to the Upbit investigation and China’s blockchain ratings announcement, investors recognized that these technical differences meant neither cryptocurrency was a direct substitute for the other—they were complementary solutions to different problems in the evolving digital economy.

BCH at $1472 with 32MB blocks vs ETH at $686 with smart contracts. looking back, the market was still mispricing which one mattered
BCH couldnt even get DeFi running properly with 32MB blocks. ETH had thousands of dApps while BCH was still arguing about satoshis vision
Ruxandra exactly. 32MB blocks and zero dev activity. ETH had thousands of dapps while BCH was still doing merch patches lol
noodle_hash 32MB blocks and zero dev activity. ETH had thousands of dapps while BCH was still arguing about block size. the market picked the chain that actually built things
32MB blocks and they still couldnt get merchant adoption. turns out block size was never the bottleneck
BCH at $1,472 vs ETH at $686 in 2018. The market cap comparison today tells you everything about which philosophy won.
block_war_vet BCH at 1472 vs ETH at 686 and now ETH is 100x ahead. the market chose programmable money over bigger blocks. not even close
block war vet BCH at 1472 vs ETH at 686 in 2018. today the gap is 100x. bigger blocks was never a scaling solution, just a political statement
amir ben-david rollups scaled eth to 100k tps while bch still argues about block size on a chain nobody uses for dapps. not even close
“Bitcoin but better” with bigger blocks vs “world computer” with smart contracts. One of these scaled by building L2s, the other just kept increasing block size.
^ BCH still hasnt figured out that bigger blocks dont solve the fundamental problems. ETH went with rollups and never looked back
32mb_club BCH still pushing bigger blocks while ETH went with rollups. one approach scaled, the other didnt. the market has spoken
BCH at 1472 and ETH at 686 in 2018. nobody thought the gap would be 100x a few years later. bigger blocks was a bandaid not a solution
foldver_42 the 100x gap was brutal. i held BCH from 1472 down to nothing because i believed the bigger blocks narrative. should have read the dev commit graphs
fork_war_vet_2 the 100x gap between BCH and ETH was brutal. holding BCH from 1472 down because of the bigger blocks narrative while ETH went on a 100x run is the most expensive wrong call in crypto history
32MB blocks prove Bitcoin Cash is digital cash
Ethereum’s smart contracts opened up new possibilities
both paths have merit – BCH for payments, ETH for dapps
CryptoPhilosopher both paths dont have merit though. BCH payments thesis died when lightning actually started working. ETH dapps carried the entire 2020-2021 cycle
Tomas R. lightning killed the BCH payments thesis but ETH dapps didnt really deliver until DeFi summer 2020. two year gap where neither was winning
Tomas R. lightning killed the BCH payments angle but ETH smart contracts carried two full bull cycles. roger ver bet on the wrong horse
32MB blocks and the chain was still empty. ETH had thousands of dapps by 2019 while BCH debated CW controversy for two years straight
1472 vs 686 in 2018 and today eth is 100x ahead. the bigger blocks debate was settled years ago, the market just took a while to fully price it in
BCH at 1472 vs ETH at 686 in May 2018. anyone who picked the bigger blocks narrative over smart contracts paid for it with a 95% drawdown
Sune K. the block size wars split the community but the market already decided. ETH went 100x, BCH went to single digits against ETH. case closed
