BTCB2 spikes to $1,799 as thin liquidity drives volatile price action

The Bitcoin Blake2 fork, known as BTCB2, surged to $1,799 per token on Sept. 5, drawing attention from traders despite trading on obscure platforms and facing technical challenges.

Origin of BTCB2

BTCB2 emerged from the BIP‑110 split that occurred on Aug. 8, 2026 at block height 961632. The split was driven by a proposal to restrict large non‑monetary data on the Bitcoin network, which was rejected by the majority of miners. The minority chain adopted the Blake2 hash function and a reduced block size to resume mining.

Exchange listings and liquidity

BTCB2’s first public listings were on Neoxa and Nonkyc.io, offering BTC, USDC and USDT pairs. Both exchanges are relatively unknown, and market‑cap aggregators such as CoinMarketCap and CoinGecko do not list BTCB2, resulting in spotty liquidity. Over the past 24 hours, Neoxa’s USDC market recorded roughly $1 million in BTCB2 trades.

Price volatility and valuation

After hitting $1,799, BTCB2’s price fell to a range of $750‑$1,000 within four hours. At a $1,000 price, the fully‑diluted valuation would be about $20.9 billion, which would place it among the top ten crypto assets by market cap if listed on a major exchange. However, current trading volume is measured in hundreds of thousands, far below the daily volumes of established top‑ten coins.

Network activity and mining

BTCB2’s hashrate has risen 30.41 % over the past week, reaching approximately 5.1 PH/s. About 60 distinct mining pools contribute to the network, with Pyblock being the largest.

Replay‑attack concerns

Because BTCB2 shares the UTXO model with Bitcoin, transactions must be split from Bitcoin to avoid replay attacks, where a BTCB2 transaction could be replayed on the Bitcoin chain. Splitting tools have been released, but the risk remains a barrier for many holders.

Outlook

BTCB2’s future price discovery will depend on broader exchange listings, improved liquidity, and resolution of replay‑attack risks. Until then, its high valuation should be viewed as speculative.
