Equity comp at Coinbase
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

If a meaningful share of your net worth sits in COIN, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with COIN's option-implied volatility.
Example: 5,000 COIN shares at $169.62 is a $848,100 position. A 30% drawdown costs $254,430; a 50% drawdown costs $424,050; a 70% drawdown costs $593,670. The calculator quantifies the trade-off between selling down (immediate capital-gains tax) and hedging (option premium drag) using COIN's option-implied volatility and your cost basis.

Coinbase equity questions
- How much COIN stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your COIN position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does Coinbase grant ISOs, NSOs, or RSUs?
- Equity compensation at Coinbase typically takes the form of incentive stock options (ISOs), non-qualified stock options (NSOs), and restricted stock units (RSUs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise. Restricted stock units are taxed as ordinary income when they vest.
- Do Coinbase RSUs use double-trigger vesting?
- No. Coinbase restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
