Withdraw amount from strategy_id.
AI agents use deallocate_earn to commit financial operations through Mcp Kraken — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Deallocating/withdrawing from an earn strategy on Kraken moves funds and commits a financial operation. While it returns funds to the spot wallet rather than sending them externally, it still constitutes a financial action with real monetary consequences. The context of a cryptocurrency exchange and sibling tools like 'allocate_earn' and 'cancel_withdrawal' confirm this is a financial operation.
From the tool's definition 'Withdraw `amount` from `strategy_id`' — this moves funds out of an earning/staking strategy on a cryptocurrency exchange
