Last year, Reddit co-founder Alexis Ohanian said that cryptocurrencies make up a small part of his investment portfolio. "NFTs are just the beginning of what's being created on top of the [Bitcoin] blockchain," says Ohanian. Ohanian is putting a lot of money towards the open source, decentralized finance platform based on smart contracts. He believes the US should move carefully in order to allow similar blockchain developments to flourish in the country.
