Coinbase's new live view for ETH2 interest is amazing. It's super powerful to see interest accrue in real time.
It's made me wonder why this isn't a more common feature of TradFi savings platforms, allowing people to see the value of standing pat and watching their wealth grow.
Cynically you could probably argue that most older banks - boasting financial stacks largely held together with COBOL and duct tape - have a couple of reasons:
1) Legacy system architectures that struggles to emit your balance, let alone stream updates to your phone
2) Absolutely terrible APR that accrue interest at a pace so glacial you would assume a live view is a static number anyway
Either way, it's a shame not to see it used more widely. Financial literacy is hard, determining active savings rates is even harder, and visualising them properly requires you to be a Chartered Accountant with unusual aptitude and a gift for story telling.
At a time when a lot of people are sitting on a glut of savings, it would be nice to show them how their money is working for them in real-time.
