If you want to invest in nostr as though it is a start up. I.e. you are looking to fund its development and eventually profit from its success. You can simply buy BTC. The developers and content creators use BTC to build nostr friendly products and services - and they earn it on here too. One person can't necessarily make the difference, but like a company going public, many of us stacking together will increasingly move the needle. And I think this applies to any other similar products and services in the future decentralised economy.
