Definition: Bitcoin ABC


(Bitcoin Adjustable Blocksize Cap) A hard fork of Bitcoin Cash in 2020. Whereas Bitcoin Cash, itself a hard fork of the original Bitcoin, relies on donations to pay for future changes, Bitcoin ABC takes a percentage of the miner's block reward to fund development. The Bitcoin ABC symbol was BCHA, while Bitcoin Cash retained BCH. In mid-2021, Bitcoin ABC was rebranded as eCash (XEC). See Bitcoin Cash and Bitcoin.
