The best projects have a large community of respected accounts frequently talking about them organically.
Hyperliquid is known for spending $0 in marketing. Because the product (+ token) does the marketing.
Imagine having @blknoiz06 @ThinkingUSD and @CryptoHayes tweeting daily about your project for free (their bags).
You need two things for this to happen:
1/ Make a product ppl use
2/ Make your (rich) users richer
Many good projects only have one. Uniswap has (1) and Apecoin/Blur did (2) but very few projects have both like Hyperliquid.
For (2) to happen, you need:
a/ Launch at low FDV
b/ Good tokenomics (reasonable allocation to team+investors etc.)
c/ Revenue
d/ Buybacks
That's it.
The playbook is simple but many founders are focused on making a quick bag for themselves in the short-term.
