The internet personality’s statement comes two weeks after the devastating crash of her cryptocurrency. On December 4, Welch launched her highly-anticipated memecoin, which flourished to a whopping $500 million on Solana betchan. However, just 20 minutes into the launch, $HAWK plunged to $60 minutes, costing some investors their “whole life savings.”
James Sallah, Welch’s attorney, confirmed the positive outcome of the SEC investigation. “The SEC closed the investigation without making any findings against, or seeking any monetary sanctions from, Hailey,” Sallah stated.
Following news of the closed investigation, the price of HAWK reportedly jumped by 25% on the decentralized exchange Meteora. Recent data shows the meme coin has a market cap of approximately $4 million with $333,000 in trading volume over a 24-hour period.

Not all cryptocurrencies are created equally, and you’ll have to do your own research into individual coins and tokens before making investments, especially if they are new. As for the technology itself, popular cryptocurrencies like Bitcoin and Ethereum rely on the blockchain to record and process transactions securely, which is widely regarded as an extremely secure platform. Criticisms of crypto include price instability and environmental concerns. According to a study by Statista, the average level of energy consumption for a single Bitcoin transaction could be the equivalent of hundreds of thousands of VISA card transactions.
People often invest in crypto in a few different ways: as a personal hobby, a wealth-building strategy, or as part of their profession. The crypto investment buzz has made hobby-level investing popular, particularly among younger investors. Here are two approaches to cryptocurrency investments:
The rewards paid to miners increase the supply of the cryptocurrency. By making sure that verifying transactions is a costly business, the integrity of the network can be preserved as long as benevolent nodes control a majority of computing power. The verification algorithm requires a lot of processing power, and thus electricity, in order to make verification costly enough to accurately validate the public blockchain. Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem, they must further consider the significant amount of electrical power in search of the solution. Generally, the block rewards outweigh electricity and equipment costs, but this may not always be the case.
In 2022, cryptocurrencies attracted attention when Western nations imposed severe economic sanctions on Russia in the aftermath of its invasion of Ukraine in February. However, American sources warned in March that some crypto-transactions could potentially be used to evade economic sanctions against Russia and Belarus.

Although it offers advantages like faster transactions and cheaper fees, it can be volatile. Traditional currency, on the other hand, is generally accepted and reliable, but it can be costly and slow for international transactions.

New Bitcoins are created by users running the Bitcoin client on their computers. The client “mines” Bitcoins by running a program that solves a difficult mathematical problem in a file called a “block” received by all users on the Bitcoin network. The difficulty of the problem is adjusted so that, no matter how many people are mining Bitcoins, the problem is solved, on average, six times an hour. When a user solves the problem in a block, that user receives a certain number of Bitcoins. The elaborate procedure for mining Bitcoins ensures that their supply is restricted and grows at a steadily decreasing rate. About every four years the number of Bitcoins in a block, which began at 50, is halved, and the number of maximum allowable Bitcoins is slightly less than 21 million. As of 2025 there were almost 20 million Bitcoins, and it is estimated that the maximum number will be reached in 2140.
Dark money has also been flowing into Russia through a dark web marketplace called Hydra, which is powered by cryptocurrency, and enjoyed more than $1 billion in sales in 2020, according to Chainalysis. The platform demands that sellers liquidate cryptocurrency only through certain regional exchanges, which has made it difficult for investigators to trace the money.
A recent 2020 study presented different attacks on privacy in cryptocurrencies. The attacks demonstrated how the anonymity techniques are not sufficient safeguards. In order to improve privacy, researchers suggested several different ideas, including new cryptographic schemes and mechanisms for hiding the IP address of the source.
On 17 February 2022, the Department of Justice named Eun Young Choi as the first director of a National Cryptocurrency Enforcement Team to help identify and deal with misuse of cryptocurrencies and other digital assets.
The first cryptocurrency was bitcoin, which was first released as open-source software in 2009. As of June 2023, there were more than 25,000 other cryptocurrencies in the marketplace, of which more than 40 had a market capitalization exceeding $1 billion. As of April 2025, the cryptocurrency market capitalization was already estimated at $2.76 trillion.
