Frequently Asked Questions

BTC (Bitcoin) is the digital asset being traded.

OTC (Over-the-Counter) refers to the method of trading Bitcoin outside of public exchanges.

OTC trades are typically large, privately negotiated transactions between buyers and sellers—often involving brokers or OTC desks—while BTC on an exchange is bought and sold publicly at market prices.

OTC allows for price discretion, reduced market slippage, and better liquidity for high-volume trades.

Exact numbers are hard to determine because OTC trades happen off-exchange and aren’t publicly reported.

However, analysts estimate that OTC volumes are substantial, sometimes matching or even exceeding exchange-traded volumes during peak market activity.

Much of the institutional and whale-level Bitcoin movement happens OTC to avoid affecting the open market price.

Yes, OTC trading is legal in most jurisdictions, as long as it follows the rules set by regulators.

This includes complying with KYC (Know Your Customer), AML (Anti-Money Laundering), and sometimes securities laws, depending on the nature of the assets involved.

Reputable OTC desks operate under financial regulations and often require identity verification and source-of-funds checks to maintain compliance.

Both OTC and P2P (peer-to-peer) allow for direct crypto trading outside centralized exchanges, but they serve different user bases and have different mechanics.

OTC is geared toward high-volume trades, often for institutions or high-net-worth individuals, and typically involves a broker or desk managing the trade.

P2P trading connects individuals directly, often on platforms like Binance P2P or Paxful—allowing them to negotiate terms and payment methods themselves.

P2P is more accessible to retail users, while OTC prioritizes privacy, liquidity, and large order execution.

BTC OTC works through direct negotiation between a buyer and a seller, usually facilitated by an OTC broker or desk.

The desk quotes a price based on market conditions, and once both parties agree, the trade is executed privately, often using escrow, third-party custodians, or direct wallet transfers.

This method is popular with institutions, miners, and whales who want to avoid moving large volumes on public exchanges, which could impact the market price.

At CustomersChain, we don’t charge a separate commission for our OTC service.

Instead, we work with a spread, which is a small difference between the buy and sell price.

This spread is based on market conditions and is fully discussed at the time of the trade.

The price we quote is all-inclusive, with no hidden or extra fees.

There is no upper limit on the amount of Bitcoin that you can buy through CustomersChain’s OTC Service.
