The site is still being built — nothing on it is final yet.Write to hi@perly.io to hear things first, or wait for the announcement.
The market sorts Bitcoin holders into ranks named after sea creatures, by how much BTC an entity holds. The bands below are the commonly used ones — the boundaries vary a little from chart to chart, and they describe addresses and entities, not verified people. Perly is a private portfolio tracker; at each rank, one thing it does earns its keep. On the home page the same ladder is a descent.
Shrimp hold less than a whole coin. On its own that is nothing; together it is the reason nobody can corner the network. For most of them Bitcoin is savings, not a trade.
Perly is built for Bitcoin, and it tracks other coins too. Record that first fill, and watch it layer.
Crabs hold one to ten. They stopped testing the water a while ago and built the position deliberately, a buy at a time — and they have usually read what it is they are holding.
Portfolios, tags and notes keep every one of those buys separate and legible.
Octopuses hold ten to fifty and have usually been through more than one cycle. Many run a node and follow the arguments about the protocol; a bad quarter has stopped surprising them.
Cost basis and average buy price, recomputed from your entries every time you edit one — including the ones you backdate.
Fish hold fifty to a hundred. In a thin market an order that size is visible in the book — which is a decent argument for not being visible anywhere else.
Row-level security is enabled and forced on every table: a query made from any other account returns nothing at all.
Dolphins hold hundreds of coins and tend to be deep in the industry — funding work, running infrastructure, teaching. At that size the position is a job rather than a bet.
Realized and unrealized PnL and ROI, computed from the transactions you entered and from nothing else.
Whales hold more than a thousand coins. Every movement of a position that size is watched, which is why the ones who have the choice stay quiet about it.
Perly holds no seed phrase, no private keys and no exchange API keys. There is nowhere in the system for them to live.
Humpbacks hold more than five thousand. There are not many of them, most were early, and not one of them found out what they held from a page like this one.
The point of a private record is that it stays a record: Perly cannot trade for you, cannot move a balance, and cannot be made to.
Above the named ranks the ladder stops being a list. The largest holders do not show themselves, and a page that respects its own privacy argument does not pretend to know them.
