Ark Invest family of funds head Katie Wood said Tuesday that BTC started the revolution and etherium has become the predominant platform for smart contracts today, saying she believes in both of these cryptocurrencies, Business Insider writes.

However, her funds are not actively trading digital collectibles, known as NFTs.

Asked which she believes in more, however, Katie Wood said she believes in both of these currencies, though they are not comparable and are “tied to different revolutions” in digital assets.

“We maintain high conviction in both,” she said.

BTC, the largest cryptocurrency by market value today, she said, has revolutionized decentralized finance and the future of the internet, known as Web 3.0, the successor to Web 2.0.

“Bitcoin is the deepest application of publicly available blockchains, the foundation of ‘self-sufficient’ digital money,” Wood wrote.

Bitcoin traded Tuesday at $8,405.60, a far cry from its record November high of about $69,000.

As for etherium, it “emerged in 2021 as the predominant smart contract platform” for decentralized finance (DeFi) and digital collectibles, known as NFTs, and is likely to get a share of the $123 trillion global money supply.

However, “while ARK is convinced of DeFi and the utility of NFTs for a variety of use cases including gaming environments, we do not currently trade NFTs in any of our strategies.”

Non-fungible tokens, or NFTs, are works of art related to blockchain technology. Their sales topped $41 billion last year. They are usually minted on the etherium blockchain, but some crypto experts, such as FTX head Sam Bankman Fried, believe other blockchains with cheaper fees are already outpacing etherium in the market.

The Wood Ark Invest fund focuses on long-term investments with a 5-year horizon.
