Dorsey founded twitter in 2006 and served as CEO of the company, but he was dismissed by twitter in 2008 for management and absenteeism.

In 2015, Dorsey returned to twitter again and continued to serve as CEO. However, as the CEO of both companies, he was attacked and worried by twitter activist investor Elliott Management Corp. in 2020.

Although it is difficult to predict the extent to which Dorsey's recent departure from twitter was influenced by Elliott, it is reported that Elliott was dissatisfied with his allocation of time between leading twitter and square at that time.

Today, block has become a financial technology company with a market capitalization of three times that of twitter.

Dorsey has long been a supporter of bitcoin. His profile on Twitter is "#bitcoin", but interestingly, he is not keen on other cryptocurrencies.

Previously, Dorsey sold his first tweet in the form of NFT for $2.9 million. After the transaction was completed, he immediately said that he would convert Ethereum's revenue into bitcoin and donate it to givedirectly.

At the bitcoin conference held in Miami last June, Dorsey once again stressed his love for bitcoin. "If I'm not in square or twitter, I'll be committed to bitcoin related work."

At this stage, block, which has multiple bitcoin and blockchain plans, is giving him the opportunity to "show his skills".

Block's financial report for the third quarter of 2021 shows that the company's total revenue is $3.845 billion, and the revenue related to bitcoin in cash app is $1.82 billion, accounting for nearly 50% of the total revenue.

However, during the reporting period, block recognized a bitcoin impairment of $6 million, and its bitcoin investment has recorded three impairments so far.
