> Is there an accessible introduction, a YouTube video perhaps, to crypto instruments beyond Bitcoin? I take you're specifically interested in what's known as "DeFi" (decentralised finance)? Multiple things going on on that front, but you could start here: https://archive.is/bJQt4 https://archive.is/bJQt4 (coincentral); this video's a pretty good overview on Ethereum's DeFi ecosystem https://www.youtube-nocookie.com/embed/k9HYC0EJU6E https://www.youtube-nocookie.com/embed/k9HYC0EJU6E and this one on what's happened in just 2020 https://www.youtube-nocookie.com/embed/qFBYB4W2tqU https://www.youtube-nocookie.com/embed/qFBYB4W2tqU DeFi, today, is poised to grow beyond Ethereum. Check out cross-chain networks like Polkadot (https://archive.is/GZVlM https://archive.is/GZVlM) and Cosmos (https://archive.is/1pWHF https://archive.is/1pWHF). matic.network (now Polygon) is another interesting side-chain network that seeks to take Ethereum tokens cross-chain. If you're looking to build a DeFi product on Ethereum, docs at 0x.org, aave.com are good places to start (since they integrate out of the box with decentralised exchanges like Uniswap, Balancer etc). Circle.com, Sendwyre.com, Simplex.com, and Nowpayments.io are some of the leading providers for fiat <-> crypto-currency transfer. I am sure Binance has some offering in this space too.
