How much Bitcoin (BTC) can you buy with 100,000 yen? Latest prices and how to buy

In recent years, Bitcoin (BTC), a representative cryptocurrency, has been attracting more and more attention. Recently, more and more people are purchasing Bitcoin in small amounts.

100,000 yen is a milestone in terms of investment funds to prepare in order to purchase a certain number of Bitcoins. However, the price of Bitcoin fluctuates greatly, and depending on the time of purchase, the amount of Bitcoin that can be purchased for the same amount can vary greatly.

In this article, we will explain in detail how to calculate the cost of purchasing 100,000 yen worth of Bitcoin, how to actually purchase it, fees, and points to note.

Current price: 13,050,000 yen

As of March 24, 2025（CoinMarketCap "Bitcoin (BTC) Price, Chart, Market Cap"）

Bitcoin prices have risen significantly following the approval of spot ETFs in the United States in 2024. At one point, the price exceeded $100,000, a milestone in dollar terms, bringing profits to many investors.

Bitcoin price and calculation formula

To calculate how much Bitcoin you can buy, you need to know the current Bitcoin price. The basic formula is:

Amount of Bitcoin available for purchase = 100,000 yen / current Bitcoin price

For example, if the price of Bitcoin is 12 million yen, the calculation formula is as follows:

100,000 yen ÷ 12,000,000 yen = 0.00833 BTC

As the price of Bitcoin fluctuates, the amount you can purchase also changes, so it is important to check the price regularly.

Bitcoin minimum purchase amount

Some domestic cryptocurrency exchanges allow you to purchase Bitcoin for as little as 1 yen, but in recent years, the minimum purchase unit has been changing due to the rise in Bitcoin's value. Also, the minimum purchase unit differs from exchange to exchange, so it is necessary to compare them. Be sure to check the rules of the exchange you are using or plan to use.

Bitcoin price trends and fluctuations

Looking back at the price trends of Bitcoin over the past few years, it recorded a peak of about 7.7 million yen in 2021, but temporarily fell below 2 million yen in early 2023. The price then rose again from the latter half of 2023, exceeding 16 million yen in December 2024.

As can be seen from these price movements, it is important to refer to past price trends in order to determine whether the current price is expensive or cheap. Understanding market trends will help you make better investment decisions.

How to purchase on a domestic exchange

The most common way to purchase Bitcoin is through a domestic cryptocurrency exchange. Major exchanges include Coincheck, bitFlyer, SBI VC Trade, and GMO Coin.

Each exchange has its own characteristics; for example, bitFlyer has high security, while Coincheck has an easy-to-use interface. First, it is important to check the website of each exchange and choose the exchange that suits you best.

You can also purchase it from overseas exchanges, but be careful

You can also purchase Bitcoin using overseas cryptocurrency exchanges (Binance, Bybit, etc.). Compared to domestic cryptocurrency exchanges, overseas cryptocurrency exchanges have lower fees and a wider variety of cryptocurrencies available.

However, overseas cryptocurrency exchanges generally do not obtain licenses as cryptocurrency exchange operators from the Financial Services Agency of Japan, and some of them are malicious and illegal operators, so you should be aware that there is a risk of trouble or losing your assets. Therefore, we generally recommend purchasing Bitcoin from domestic cryptocurrency exchanges.

Consider the fees when purchasing

When purchasing Bitcoin at a cryptocurrency exchange, fees will be charged. There are the following types of fees:

• Spread: The difference between buying and selling prices
• Transaction fees: Varies between spot trading and sales
• Deposit/Withdrawal Fees: Varies by exchange

It's important to take these fees into account and calculate how much Bitcoin you can actually buy.

Benefits of investing from 100,000 yen

You can start investing in Bitcoin with as little as 1 yen, but if you want to make a certain amount of profit, an investment amount of 100,000 yen is one guideline. Also, with an eye toward long-term asset formation, it may be a good strategy to save 100,000 yen every month.

Bitcoin has seen a significant increase in price in recent years. If you had saved up Bitcoin every month from five years ago (2020, 1 BTC = approximately 1 million yen), you would have made a large profit as of 2025 (approximately 12 million yen)

Beware of price fluctuation risks

Bitcoin is characterized by its high volatility and large price fluctuations. For example, if you invest 100,000 yen, it is difficult to predict what its value will be six months from now. It is important to understand the risk of price declines and to purchase at an amount that is appropriate for your capital.

About taxes and tax returns

If you make a profit from trading Bitcoin, you may need to file a tax return. Even if you only invest 100,000 yen, if you make a profit, it may affect your taxes. Be sure to have a good understanding of taxes and do not neglect to complete the necessary procedures.

In this article, we have explained in detail the points and risks you should remember when purchasing 100,000 yen worth of Bitcoin. Let's summarize the main points at the end.
