What Is Bitcoin (BTC)?

Bitcoin is the first cryptocurrency, launched in 2009 by the pseudonymous Satoshi Nakamoto. It runs on an open proof-of-work network with no issuer and no central operator, and its supply is capped at 21 million coins.

Transactions are grouped into blocks that are added to the chain roughly every ten minutes. The network fee is charged for the space a transaction takes up in a block, not for the amount being sent, so the size of the payment itself does not drive the cost.

Bitcoin is the largest cryptocurrency by market capitalisation and the asset most widely supported by exchanges, wallets and custody providers. Since 2024 it is also held through spot exchange-traded funds in the United States, which brought it into regulated investment portfolios.

For businesses this matters in one practical way: BTC is the coin almost every crypto user already holds, so accepting it covers the widest part of the crypto audience with a single payment method.

Why Accept Bitcoin Payments

Lower fees than credit cards

Card payments often take 2–3% of the transaction amount. PassimPay processing fees start at 0.5%, with an optional 0.2% when automatic conversion is enabled. On large invoices and recurring payments the difference adds up.

Protection from volatility

Incoming BTC payments can be converted into USDT or USDC automatically at the moment of receipt, so the amount you receive is not exposed to market movement.

Built for subscriptions

Assign a permanent BTC deposit address to each customer. They pay to the same address every time, which works for subscriptions, memberships and regular B2B billing, with no stored card details and no expired cards.

No hidden fees

PassimPay has no monthly subscription fee or hidden platform charges. Businesses can accept BTC payments with free setup and pay only for completed transactions.

Fast API integration

Use the PassimPay BTC payment gateway API to connect Bitcoin payments to your website in a few hours. PassimPay also provides 12 ready-made CMS plugins, including WordPress, Shopify, WooCommerce and Magento 2.
