ChangeTip
ChangeTip integrates payment processing with social media and the web at large to transform the idea of a "share" into a method of financial appreciation, redefining the way people think about purchasing goods and services. Instead of broadcasting a tip as a bitcoin transaction, a separate ledger is kept by ChangeTip, only pushing on-chain transactions when a user withdraws funds from the service. Tipping has been made possible on GitHub, Google+, Reddit, StockTwits, Tumblr, Twitter and YouTube.
History
ChangeTip was founded on December 17th, 2013.[1] It gained significant notoriety in November 2014, when tipping small amounts of bitcoin became a viral practice on Reddit and Twitter, causing exponential growth in users and tips. This has caused significant use of bits as a unit of bitcoin.
