A cryptocurrency (colloquially crypto) is a digital currency designed to work through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it https://lise-dautry.com/.
Despite these risks, cryptocurrencies have seen a significant price leap, with the total market capitalization rising to about $2.4 trillion. Despite the asset’s speculative nature, some have created substantial fortunes by taking on the risk of investing in early-stage cryptocurrencies.
Memecoins are a category of cryptocurrencies that originated from Internet memes or jokes. The most notable example is Dogecoin, a memecoin featuring the Shiba Inu dog from the Doge meme. Memecoins are known for extreme volatility; for example, the record-high value for a Dogecoin was 73 cents, but that had plunged to 13 cents by mid-2024. Scams are prolific among memecoins.

In 2022, RenBridge – an unregulated alternative to exchanges for transferring value between blockchains – was found to be responsible for the laundering of at least $540 million since 2020. It is especially popular with people attempting to launder money from theft. This includes a cyberattack on Japanese crypto exchange Liquid that has been linked to North Korea.
DeFi tokens are the backbone of decentralized finance (DeFi) applications. They allow users to lend cryptocurrencies and earn interest or borrow against them. For instance, the Ethereum-based lending platform Compound’s (COMP) token is a DeFi token that is used for these purposes.
Crypto marketplaces do not guarantee that an investor is completing a purchase or trade at the optimal price. As a result, as of 2020, it was possible to arbitrage to find the difference in price across several markets.
The first chain to launch smart contracts was Ethereum. A smart contract enables multiple scripts to engage with each other using clearly defined rules, to execute on tasks which can become a coded form of a contract. They have revolutionized the digital asset space because they have enabled decentralized exchanges, decentralized finance, ICOs, IDOs and much more. A huge proportion of the value created and stored in cryptocurrency is enabled by smart contracts.
On 23 March 2023, the SEC issued an alert to investors stating that firms offering crypto asset securities might not be complying with US laws. The SEC argued that unregistered offerings of crypto asset securities might not include important information.
In terms of annual consumption (kWh/yr), the figures were: Polkadot (70,237), Tezos (113,249), Avalanche (489,311), Algorand (512,671), Cardano (598,755) and Solana (1,967,930). This equates to Polkadot consuming 7 times the electricity of an average U.S. home, Cardano 57 homes and Solana 200 times as much. The research concluded that PoS networks consumed 0.001% the electricity of the bitcoin network. University College London researchers reached a similar conclusion.

This has led some, including YouTube cryptocurrency investigator Coffeezilla, to accuse Ms Welch of scamming investors with a “pump and dump” – where the people behind a coin hype up its price before launch, then sell it for profit.
“It was one of those things that just happened, and I feel sorry for everybody that just lost money,” Welch told Vanity Fair in a recent interview. “You got to be really careful what you tie your name to, and you definitely need to know what you’re getting yourself into when you agree to do it. That’s something I definitely should have done beforehand.”
Fans and investors have accused Ms Welch and her team of “misleading” and “betraying” them and suggested the launch had been a “rug pull” – where promoters of a cryptocurrency draw in buyers, only to stop trading activity and make off with money raised from sales.
Welch and the team at overHere Ltd, which was responsible for creating the $HAWK coin, hopped on a Twitter Spaces stream on the night of the launch to try to explain what happened. It went…poorly. Crypto scam reporter and YouTuber Coffeezilla got on the mic and called out the creators for allegedly selling a sizable chunk of the tokens to insiders before launch while only releasing 3% to the public for trading as well as paying themselves high transaction fees. The result looked a lot like a rug pull that saw a bunch of Hawk Tuah fans left holding the bag.
The launch of Welch’s coin comes as crypto has been in the midst of a resurgence thanks largely to the soaring price of Bitcoin, which recently topped $100,000 for the first time. President-elect Donald Trump’s embrace of crypto has also injected renewed enthusiasm into the industry.
