Separate a target price from execution conditions
The name 114514 alone does not identify an asset or trading market. This article does not certify listings or supported currencies for a particular mint; it organizes quantities, order conditions, costs and records for an exit plan. Selling half at twice the price can be an arithmetic example but cannot guarantee execution or capital recovery.
Record the network and mint, then verify a route supporting that asset, the destination’s supported networks and currencies, minimum quantities and costs. A matching currency name alone does not establish transfer compatibility.
A stop order does not protect principal
FINRA’s order-types explanation concerns stocks but illustrates the distinction between a trigger and execution price. A stop that becomes a market order does not guarantee the stop price; a limit constrains price but may not execute. This source does not establish that a crypto service offers those features.
| Feature to verify | Condition | Remaining uncertainty |
|---|---|---|
| Market order or swap | Exchange a quantity on available routes | Price impact and changes after quotation |
| Limit order | Specified price condition | Price not reached or no counterparty |
| Stop or trailing stop | Trigger after a price condition | Execution price and service availability |
Moving a stop to the purchase price still leaves losses from gaps, vanished liquidity, trading interruptions and costs. Do not base a plan on an automated feature that the actual service has not confirmed.
Calculate partial-sale recovery after costs
Assume 100,000 tokens with total acquisition cost ¥10,000 and a displayed price of ¥0.20. Selling 50,000 actually produces ¥9,600 gross, with ¥200 separate costs. These are hypothetical inputs, not a real token outcome.
| Item | Calculation | Result |
|---|---|---|
| Half the position at displayed price | 50,000 × ¥0.20 | ¥10,000 |
| Actual net proceeds | ¥9,600 − ¥200 | ¥9,400 |
| Difference from initial funding | ¥9,400 − ¥10,000 | −¥600 |
| Remaining units | 100,000 − 50,000 | 50,000 |
Even at twice the acquisition unit price, costs and execution may leave initial funding unrecovered. The remaining 50,000 units still have economic value; they are not free money. If the remainder has zero recovery, the total loss in this example is ¥600.
Check failures before loosening price tolerance
Uniswap’s swap documentation explains transactions failing when conditions such as minimum output are unmet. This is a mechanism reference; verify the actual route separately.
Distinguish expired quotations, price conditions, insufficient fee funds, token restrictions and service problems. Widening tolerance accepts worse terms and is not a universal fix. For rising, flat and falling-price scenarios, compare net proceeds for the full and partial quantities and record which planned cash payments would be underfunded.
Record exchanges before conversion to yen
This tax section principally assumes an individual resident in Japan. The NTA FAQ of December 26, 2025, covering sales, crypto-to-crypto exchanges and income classification addresses exchanges as well as yen sales. Distinguish ordinary miscellaneous-income treatment from business-related and other cases; no yen withdrawal does not establish no filing duty.
| Record | Purpose |
|---|---|
| Time, mint, network and units | Identify the asset and transaction |
| Received asset and yen valuation evidence | Determine exchange consideration |
| Acquisition basis, costs and transaction ID | Reconcile profit calculations with records |
The employee filing exception has additional conditions and is not determined solely by a ¥200,000 profit figure. Check current-year materials and individual facts with a tax professional where necessary.
