Frequently Asked Questions

What is Web3?

Web3 is the concept of a decentralized internet built on blockchain technology, where users own their data and digital assets rather than relying on centralized platforms. It encompasses cryptocurrencies, DeFi, NFTs, DAOs, and decentralized identity — aiming to shift power from corporations to individuals.

What is a Bitcoin ETF and why is it important?

A Bitcoin ETF (Exchange-Traded Fund) allows investors to gain exposure to Bitcoin through traditional brokerage accounts without directly holding cryptocurrency. The SEC's approval of spot Bitcoin ETFs in January 2024 was significant because it legitimized Bitcoin as an investment asset and opened the door for trillions of dollars in institutional capital.

Which major companies are using blockchain?

BlackRock and Fidelity launched Bitcoin ETFs. JPMorgan uses its Onyx blockchain for institutional payments. Visa and Mastercard support crypto transactions. PayPal launched its PYUSD stablecoin. Starbucks experimented with NFT loyalty programs. These integrations signal that blockchain is transitioning from experimental to production infrastructure.

What is MiCA regulation?

MiCA (Markets in Crypto-Assets) is the European Union's comprehensive regulatory framework for crypto assets, adopted in 2023. It establishes rules for stablecoin issuers, crypto exchanges, and wallet providers, providing legal certainty that encourages institutional participation while protecting consumers.
