BTCB2 Soars to $1,799 Amid Thin Liquidity and Replay Risks
A Bitcoin fork called BTCB2 has seen its price soar to $1,799 after a chain split occurred on August 8, 2026. The chain split was triggered by a disagreement over BIP-110, which restricted non-monetary data. The majority of the SHA-256 hashrate did not support this plan, resulting in a network fork.
The new chain, Bitcoin Blake2, initially struggled due to its block size and difficulty adjustment issues. However, developers have since changed the network's proof-of-work to work with the Blake2 hash function and shrunk its block size, allowing it to be mined with compatible ASIC mining machines.
BTCB2 has been listed on two relatively unknown exchanges: Neoxa Exchange and Nonkyc.io. Despite the lack of major exchange listings, the fork's price has reached an all-time high against USDC, but its valuation is considered hypothetical due to thin liquidity and replay attack risks. The UTXO (unspent transaction output) must be split away from genuine BTC to avoid potential losses.
