BTC / English guide
Bitcoin · Understand the coin
Bitcoin is a peer-to-peer payment network. BTC is its native asset, and transactions are recorded on a shared blockchain without a central account operator.
What is it used for?
BTC can be transferred between wallets. Mining and proof of work help the network agree on transaction history.
What to check
Understand wallet custody, transaction fees and confirmation requirements before transferring funds.

BTC / INSIGHTS
Read the numbers
What does market capitalization tell me?
Market capitalization relates the unit price to the circulating supply. A low unit price alone does not mean a coin is cheap. The reported market cap and the estimate below can differ because of timing, rounding or supply methodology.
- 時価総額
- $1.64兆
- Price × circulating supply (estimate)
- $1.64兆
How much supply is circulating?
Circulating supply estimates units available in the market. Total supply includes existing units that may not circulate. Maximum supply is a reported ceiling; a missing value does not establish unlimited supply. This is not a token unlock schedule.

What is fully diluted valuation?
FDV values the provider’s fully diluted supply at the current price. Compare it with market cap to understand the difference in supply assumptions. It is not a future valuation or a price forecast.

Does trading volume mean I can sell easily?
24-hour volume measures reported trading activity. Dividing it by market cap puts that activity in context. It does not measure order-book depth, spreads or the execution price available for your trade.

Why can the two charts show different prices?
The history chart uses collected CoinMarketCap observations. The TradingView chart, where available, uses its displayed exchange and pair. Markets, currencies and update times can differ; gaps in collected history are left visible.
Which network and contract should I use?
Use the asset’s official documentation and your destination’s supported network. A matching ticker is not enough. The provider’s network record below is a reference, not a complete list of supported transfer routes.
A platform or token contract is not provided in this snapshot. This does not by itself prove that the asset has its own blockchain.
