On April 24, 2025, the market capitalization of Bitcoin reached $1.847 trillion, ranking sixth among global assets, surpassing silver and Amazon. BTC is the abbreviation for Bitcoin, a decentralized cryptocurrency. Bitcoin was proposed by Satoshi Nakamoto in 2008 and officially came into existence in 2009. It is based on blockchain technology, serving as a distributed, public ledger that records all Bitcoin transactions. Bitcoin is not issued by a specific currency institution but is generated through specific algorithms and extensive computation, with a total supply limit of 21 million coins, which gives it scarcity. Bitcoin supports global 24/7 trading, but trading is not allowed within China. It is viewed as a means of storing value and has attracted many investors and speculators, gaining significant attention due to its scarcity and high value. Online, 'BTC' is commonly used to refer to Bitcoin, making it easier to cite in financial news, cryptocurrency discussion forums, and social media.
