Robinhood Chain. You pay in USDG, and your position is a token in your own wallet.
No. You pay the full amount when you buy, so there is no margin and nothing to liquidate. A big move against you still lowers the value of your position.
What you put in. Never more.
A small daily cost that lowers the token's value the longer you hold it. It is set from each stock's volatility, so calm stocks cost less to hold than wild ones, and Bear² costs more than Bull² because it can't be hedged. It's shown before you buy.
Up to 4×. Bear² keeps gaining as the stock falls, down to a floor set for each market: −50% on NVDA, TSLA and PLTR (up to 4×), −40% on AAPL (up to 2.8×) and −30% on SPY (up to 2×).
You can still sell. Prices use the latest oracle price with wider spreads, and new buys pause if that price gets too old.
The Bear² vault is built to hold enough cash to pay every Bear² token at its maximum value, and it blocks new buys before that limit is reached.
