Business Organization and Nature of Operations	Note 1 - Business Organization and Nature of Operations BTCS Inc. (formerly Bitcoin Shop, Inc.), a Nevada corporation (the “Company”) was incorporated in 2008. In February 2014, the Company entered the business of hosting an online ecommerce marketplace where consumers can purchase merchandise using digital currencies, including bitcoin and is currently focused on blockchain and digital currency ecosystems. In January 2015, the Company began a rebranding campaign using its BTCS.COM domain (shorthand for Blockchain Technology Consumer Solutions) to better reflect its broadened strategy. The Company released its new website which included broader information on its strategy. In late 2014 we shifted our focus towards our transaction verification service business, also known as bitcoin mining, though in mid-2016 we ceased our transaction verification services operation at our North Carolina facility due to capital constraints. The Company is an early entrant in the Digital Asset market and one of the first U.S. publicly traded companies to be involved with Digital Assets and blockchain technologies. Subject to additional financing, the Company plans to create a portfolio of digital assets including bitcoin and other “protocol tokens” to provide investors a diversified pure-play exposure to the bitcoin and blockchain industries. The Company intends to acquire digital assets through: open market purchases and participating in initial digital asset offerings (often referred to as initial coin offerings). Additionally, the Company may acquire digital assets by resuming its transaction verification services business through outsourced data centers and earning rewards in digital assets by securing their respective blockchains. Reverse Stock Split and Amendment to Certificate of Incorporation On February 13, 2017, the Company filed a Certificate of Amendment to its Articles of Incorporation with the Secretary of State of Nevada to implement a reverse stock split at a ratio of one-for-60. The reverse stock split became effective immediately. The Reverse Stock Split reduced the number of outstanding shares of Common Stock from 952,756,004 shares to 15,879,267 shares as of December 31, 2016. All per share amounts and outstanding shares of Common Stock including stock options, restricted stock and warrants, have been retroactively adjusted in these consolidated financial statements for all periods presented to reflect the 1-for-60 Reverse Stock Split. Further, exercise prices of stock options and warrants have been retroactively adjusted in these consolidated financial statements for all periods presented to reflect the 1-for-60 Reverse Stock Split. Numbers of shares of the Company’s preferred stock and convertible securities were not affected by the Reverse Stock Split; however, the conversion ratios have been adjusted to reflect the Reverse Stock Split.
