Why do all cryptocurrencies rise and fall together

The very first cryptocurrency was Bitcoin. Since it is open source, it is possible for other people to use the majority of the code, make a few changes and then launch their own separate currency pa online lottery. Many people have done exactly this. Some of these coins are very similar to Bitcoin, with just one or two amended features (such as Litecoin), while others are very different, with varying models of security, issuance and governance. However, they all share the same moniker — every coin issued after Bitcoin is considered to be an altcoin.

In January 2024 the SEC approved 11 exchange traded funds to invest in Bitcoin. There were already a number of Bitcoin ETFs available in other countries, but this change allowed them to be available to retail investors in the United States. This opens the way for a much wider range of investors to be able to add some exposure to cryptocurrency in their portfolios.

Play-to-earn (P2E) games, also known as GameFi, has emerged as an extremely popular category in the crypto space. It combines non-fungible tokens (NFT), in-game crypto tokens, decentralized finance (DeFi) elements and sometimes even metaverse applications. Players have an opportunity to generate revenue by giving their time (and sometimes capital) and playing these games.

It also comes with promises of decreased friction, with ample information exchanged to allow full use of SCA exemptions and risk analysis. There are improvements to how data is exchanged between issuer and merchant, including reducing challenge-induced friction for higher risk transactions. Merchants and issuers will also be able to use WebAuthn and SPC (Secure Payment Confirmation) to give consumers more options, such as biometric authentication and passkeys.

In Australia, legislation has remained largely the same since 2019. Although their version of SCA was announced after the EU’s PSD2, they managed to implement a similar scheme before the EU – as a single country rather than a union of several, Australia was able to respond more quickly. However, this only applies to merchants found to have high fraud rates in the previous quarter.

When AusPayNet introduced the CNP Fraud Mitigation Framework back in 2019, one of the biggest challenges was that 3DS 2 had very bad performance, especially in relation to 3DS v1. It’s not clear why that was, but maybe this is why eftpos decided to build its own Directory Server – to improve authentication rates, knowing that 3DS 1 was going to go.

From a business perspective, it’s helpful to think of blockchain technology as a type of next-generation business process improvement software. Collaborative technology, such as blockchain, proclaims the ability to improve the business processes that occur between companies, radically lowering the “cost of trust.” For this reason, it may offer significantly higher returns for each investment dollar spent than most traditional internal investments.

Nonfungible tokens (NFTs) are minted on smart-contract blockchains such as Ethereum or Solana. NFTs represent unique assets that can’t be replicated—that’s the nonfungible part—and can’t be exchanged on a one-to-one basis. These assets include anything from a Picasso painting to a digital “This is fine” dog meme. Because NFTs are built on top of blockchains, their unique identities and ownership can be verified through the ledger. With some NFTs, the owner receives a royalty every time the NFT is traded.

Cryptography is the second component. This is the process of encrypting data and changing it to an unreadable format that only someone who knows the secret key can read or decrypt. This technology, which uses a complex public and private digital key system, safeguards cryptocurrencies like Bitcoin.
