Bitcoin did not register the highest number of addresses that actively sent or received BTC coins on the blockchain in April 2025. Indeed, Bitcoin was outperformed by TRON (TRX), a cryptocurrency that once was a part of Ethereum and is mostly associated with a protocol for hosting Tether and Decentralized Finance. Bitcoin reached an average of nearly 670,000 addresses that month - a figure that somewhat resembles how many unique users were actively buying or selling BTC. By comparison, TRON reached a figure of 2.4 million active addresses.

The number of addresses that actively sent or received Bitcoin on the blockchain peaked in April 2021, nearly reaching *** million on a single day. In the following months, this number varied dramatically from day to day, reaching around ******* addresses at is lowest point. Bitcoin has a limited supply, as it is programmed to have a maximum supply of ** million coins at most. By late 2022, more than ** percent of this maximum limit was reached.

Decentralized Finance users reached a peak of **** million unique users in 2024, whereas figures in 2025 are considerably lower. This according to a network crawling code that tries to measure the number of unique user addresses involved in buying or selling specific projects associated with DeFi. For example, the code lists data fetching commands associated with Uniswap and Aave — two DeFi protocols with a market cap that was higher than one billion U.S. dollars in March 2022. As Decentralized Finance — much like cryptocurrencies or NFTs — are not being tracked by an official government, these procedures try to measure "network activity". Such activity on the Ethereum blockchain/network, the most used blockchain for DeFi, or elsewhere — tend to be the only source of information on the market size of these topics. However, the source does acknowledge the numbers shown are not without their potential flaws. DeFi in 2025 is relatively small-scale Often remarked as a potential breakthrough trend for 2024, the TVL (total value locked) of DeFi in 2025 reveals a market that is much smaller than in 2021. The amount of money stored in Decentralized Finance was worth about ***** billion U.S. dollars by May 2025, compared to *** billion U.S. dollars at the end of 2021. Two reasons can be named for this decline. First, the overall cryptocurrency markets had witnessed several dramatic moments. Prices declined after the crash of stablecoin LUNA, and the sudden collapse of crypto exchange FTX in 2022. In 2023, the United States government handed out one of its largest ever corporates fines to Binance — the world's largest crypto exchange. Second, analysts believe the high yield on U.S. Treasury bonds in 2025 when compared to DeFi yields negatively impacted the young industry — as these bonds pose lower risk than DeFi. DeFi use cases: Supporting crypto investments Decentralized Finance hopes to offer different digital financial services, which are run by a community in a so-called decentralized autonomous organization (DAO) away from banks or governments. These services can include asset management, money lending, or trading, potentially making it possible to offer services that traditional finance cannot do. By May 2025, however, DeFi focused on two main use cases: Liquid staking and money lending. These processes are there to support crypto investors, specifically. The market size of insurance within Decentralized Finance, for example, was much smaller in comparison.

Despite the growth and prominence of mobile messengers and chat apps, e-mail is an integral part of daily online life. In 2023, the number of global e-mail users amounted to **** billion and is set to grow to **** billion users in 2027. Global e-mail audiencesIn 2023, approximately *** billion e-mails were sent and received every day worldwide. This figure is projected to increase to over *** billion daily e-mails in 2027. As of July 2022, Apple Mail Privacy accounted for over half of the e-mail opens, while mobile use of e-mails saw a significant decrease in their market shares. Apple MPP e-mail app was the most popular e-mail client, accounting for ** percent of e-mail opens. Gmail, the free e-mail service owned by Google, was ranked second with a ** percent open share. Malicious mailMany online users use e-mails for website and newsletter signups and brace themselves for the inevitable flood of spam and marketing communications. Whereas most unwanted e-mails are annoying yet ultimately benign, consumers are right to be wary of malicious e-mail that can be used to compromise their digital accounts and devices. In 2023, ** percent of fraud reports in the United States related to cases in which victims were contacted via e-mail.
