Bitcoin broke above $100,000 for the first time on Thursday as the election of Republican Donald Trump as president fuelled bets that his administration will create a friendly regulatory environment for cryptocurrencies.

The world’s biggest and best-known cryptocurrency has more than doubled from this year’s low of $38,505 and is up over 50% since Trump’s sweeping election win in early November.

Here are key events in bitcoin’s journey towards $100,000 and beyond:

2008: Satoshi Nakamoto, the pseudonym used by the cryptocurrency’s presumed developer, introduces the concept of bitcoin

2010: The first retail transaction takes place when a user pays 10,000 bitcoin for two Papa John’s pizzas

2013: As bitcoin’s popularity grows, Cameron and Tyler Winklevoss, co-founders of crypto exchange Gemini, file their first application with the U.S. Securities and Exchange Commission to create a spot bitcoin ETF.

Grayscale Investments launches the Bitcoin Investment Trust, an open-ended private bitcoin trust.

2016: The Winklevoss brothers adjust their application numerous times, such as the exchange on which the product would be traded. They also file amendments naming State Street as administrator. Grayscale files with the SEC to convert its bitcoin trust into a spot bitcoin ETF.

2017: The SEC rejects the Winklevoss application on the grounds bitcoin markets were not mature enough. Grayscale withdraws its first attempt to convert its trust into an ETF, saying the regulatory environment was not developed enough.

2018: The SEC rejects the Winklevoss twins’ second application to launch a spot bitcoin ETF, saying cryptocurrency exchanges do not have the necessary controls to prevent manipulation.

2020: Grayscale transforms its trust into an SEC-reporting entity, and its shares begin trading on the pink sheets, for stocks that trade over the counter. Although not an ETF, it is the first publicly traded bitcoin fund in the U.S.

2021: The first spot bitcoin ETF launches in Canada. Gary Gensler replaces Jay Clayton as SEC chair in April.

In October, the SEC approves the ProShares Bitcoin Trust listed on the Chicago Mercantile Exchange, noting the CME has a satisfactory mechanism for surveilling abuse in the futures market. It is the first U.S.-listed futures-based bitcoin ETF, accumulating $1 billion in assets within its first days of trading – faster than any other ETF.

Also in October, Grayscale again submits an application to the SEC to convert its trust into a spot bitcoin ETF.

2022: The SEC rejects several applications from would-be spot bitcoin ETF issuers, including SkyBridge, Fidelity and Bitwise. The SEC also rejects Grayscale’s application, prompting the company to sue the agency.

Amid crashing crypto prices, multiple crypto companies file for bankruptcy, including Three Arrows Capital, Celsius Network and FTX, whose founder Sam Bankman-Fried is also charged with fraud.
