In short
After a purchase, what matters is not tracking the price but keeping records and checking settings. Save the transaction history, review two-factor authentication and withdrawal settings, and decide how you will total results. Doing this at the start avoids the situation where the history cannot be reconstructed later.
Key points
- Save the trade history straight away; reconstructing it later is always painful
- Re-check two-factor authentication and withdrawal settings after you buy
- Put the annual totalling and filing check in your calendar
- A habit of checking the price constantly tends to make decisions worse
Definition
The work that follows a first crypto purchase: preserving records, re-checking security settings, and preparing for the tax side.
Records first. When, which asset, at what price, how much. Most exchanges let you download your trade history, so make saving it a habit after each purchase. Switch providers or see a service shut down and the old history may become unobtainable. Reaching the point of calculating a year's result with no history is a genuinely common situation.
Then security. Now that there are assets in the account, the settings mean something different. Check that two-factor authentication is on, whether you can use an authenticator app rather than SMS, whether the provider supports whitelisting withdrawal addresses, and whether you actually receive its email notifications. Accounts with assets in them are the ones attackers target.
Third, preparing for tax. Gains on crypto in Japan are in principle miscellaneous income, and depending on your circumstances a return may be required. Sales are not the only trigger — swapping crypto for crypto and paying with crypto also realise gains and losses. Decide how you will store the history on the assumption that you will total it and check your filing position once a year. Consult the National Tax Agency's guidance, and a tax professional for anything unclear.
Finally, about watching the price. It is natural to want to after buying, but frequent checking almost never improves a decision. What it usually produces is reacting to short-term moves, trading repeatedly, and accumulating nothing but fees and spread. Decide in advance how often you will look.
Watch out for
- · Without saved history, the year's result may be impossible to reconstruct
- · Tax comments here are a general orientation, not tax advice
- · An unrealised gain on screen is not a realised one
Frequently asked questions
Is it fine to leave what I bought on the exchange?
Leaving it there exposes you to the provider failing or freezing withdrawals; moving it to your own wallet puts the entire key-management burden on you. Both carry risk — understand the mechanics before choosing.
