2019 has been a historic year for cryptocurrency and blockchain technology.

Global state leaders such as President of the People’s Republic of China Xi Jinping and the President of the United States Donald Trump have made public statements addressing the dynamics of this revolutionary tech. Traditional tech companies such as messaging app giant Telegram and social media giant Facebook have made bold promises to integrate crypto into their line of products and services.

All this is just scraping the surface of all that went on in crypto-land over the past 12 months. From our family to yours, the CoinDesk Research team presents you with what we believe are the 10 most influential events of 2019. In a later post, we’ll give a sneak peak at what we’re expecting for 2020.



Key events charted against the bitcoin price and searches for bitcoin on Google

After multiple failed attempts, the second largest blockchain in the world by market capitalization executed its sixth system-wide upgrade, also called a hard fork. Dubbed Constantinople, the hard fork was executed as two upgrades, one after the other, in order to patch a critical vulnerability discovered mere hours before the upgrade was scheduled for activation.

2. Binance hacked – May 7

$40.7 million in bitcoin was stolen from the world’s largest cryptocurrency exchange by volume, Binance. Using funds from a separate pool of Binance resources called the Secure Asset Fund for Users (SAFU), all losses were refunded to users by the startup. CEO of the company Changpeng Zhao said in a letter at the time: “In this difficult time, we strive to maintain transparency and would be appreciative of your support.” Market reaction to this hack resulted in bitcoin prices dropping almost $300.

3. BitMEX flash crash – May 17

A sudden and large sell order for bitcoin through cryptocurrency exchange Bitstamp caused bitcoin prices to drop overnight by 15 percent. Going from $7,700 to $6,600 in just 15 minutes, the positive mood amongst cryptocurrency traders changed drastically overnight. The cause of the flash crash is still highly speculated and debated in the crypto industry.

4. Libra unveiled – June 18

This summer, social media giant Facebook unveiled its first and only cryptocurrency project called Libra. Libra is architected to be a permissioned blockchain network able to facilitate cross-border payments through its “low-volatility” cryptocurrency. Shortly after the Libra unveiling, U.S. regulators called on Facebook CEO Mark Zuckerberg to testify before Congress about the project. How Libra development will continue moving forward in spite of regulators’ concern and hesitation is still to be seen in 2020.

The Chairman of the U.S. Federal Reserve Jerome Powell gave a testimony about Libra before the Senate Banking Committee. While he said the project raised “a lot of serious concerns,” Powell also made comparisons driving the narrative of bitcoin as digital gold. Crypto industry figureheads such as CEO of Digital Currency Group Barry Silbert tweeted at the time, “How far we’ve come,” in response to Powell’s statements about bitcoin.

This transaction 'flippening' is a milestone for the world’s second largest blockchain network.

6. Bakkt debuts bitcoin futures – Sept. 23

The Intercontinental Exchange-backed bitcoin warehouse, Bakkt, finally launched in September after several delays and over a year of questioning from U.S. regulators. Bakkt opened its doors offering physically-settled bitcoin futures for the first time to U.S. institutional investors. Three months into its launch bitcoin futures trading volumes on Bakkt hit a record high of $124 million.

The most lucrative initial coin offering (ICO) in history was conducted by EOS blockchain creator, Block.One. This year, the charges laid against the startup by the U.S. Securities and Exchange Commission for its ICO sale, which reportedly raised $4.1 billion, were finally settled. The penalty? Block.One was fined by the SEC and required to payback 0.58% of the initial raise, which amounted to $24 million.

8. SEC halts Telegram token offering – Oct. 11

The second largest token offering in history was conducted by messaging app giant Telegram. After raising a reported $1.7 billion for its “TON” ICO, Telegram was scheduled to launch its cryptocurrency this October. However, the U.S. Securities and Exchange Commission sued the company for its unregistered securities sale and ordered a halt to token distribution. Charges laid against Telegram by the SEC have yet to be settled.

President of the People’s Republic of China, Xi Jinping, gave his first in-depth remarks about blockchain technology this year. Unlike most other state leaders, Jinping encouraged China to “seize the opportunity” afforded by blockchain. He stressed that implementation of “the rule of law” into blockchain systems was integral to the technology’s development. To this end, China is currently developing a digital version of its national currency, the renminbi.

10. ERC20 transactions surpass ETH – Nov. 10
