Remember the last time you went on vacation? After locking the door and heading toward your car, you likely turned back abruptly to ensure the lock was secure before continuing your journey.Financial markets, led by a range of human emotions, exhibit similar behaviors. After a convincing move beyond a long-held resistance, assets typically return to confirm the validity of the breakout. That serves as a test of the strength of the former resistance-turned-support, following which bigger rallies unfold.The "breakout and retest play" phenomenon is well-known across asset classes. Bitcoin's (BTC) ongoing sell-off might be just that – a healthy retest of the breakout point or the former resistance-turned-support of $73,835 breached in November.In other words, the downward momentum could run...

MetaMask, the popular self-custodial crypto wallet for the Ethereum (ETH) network, shared a flurry of announcements on Thursday, aimed at improving its wallet's user experience.Part of Metamask's revamped roadmap includes adding smart contract capabilities to its current wallet. At the moment, MetaMask is an Externally Owned Account (EOA), a type of wallet that is controlled by a public and a private key. One of the main downfalls with EOAs is that it is subject to human error, meaning if you forget your private key, you lose your crypto holdings in that account forever. The other type of wallet that exists on Ethereum are Contract Accounts (CAs), which are controlled by code and have recovery mechanisms in place and security checks...

The U.S. Securities and Exchange Commission (SEC) is officially washing its hands of memecoins.The federal securities regulator said that memecoins — which it defined as a “type of crypto asset inspired by internet memes, characters, current events or trends for which the promoter seeks to attract an enthusiastic online community to purchase the memecoin and engage in its trading” — are more like collectibles than securities, according to a staff statement from the SEC’s corporate finance division published on Thursday. Because memecoins have “limited or no use or functionality,” they do not meet the definition of a security under the Howey Test and are therefore outside the SEC’s jurisdiction.The statement is a formalization of comments made by Commissioner Hester Peirce — the...
