Bit-Z offers its platforms to users in a wide range of countries around the world, including the US. However, users in some countries are unable to use the platform, so contact Bit-Z directly to find out whether you’re legally able to access the exchange from your country of residence.

Which payment methods are accepted?

Bit-Z’s exchange platform only offers crypto-to-crypto trading, so the only way to deposit funds into your account is via cryptocurrency transfer.

However, if you’re using the OTC service, the accepted currencies are US dollars (USD), Chinese yuan (CNY) and Danish krone (DKK). The OTC platform accepts the following payment methods:

  • Bank transfer

How fast will my funds be available?

The time it will take for the funds you transfer into and out of your account to become available will vary depending on network congestion and the amount of confirmations required to complete a transaction.

If transferring fiat currency to place an OTC trade, transfer times vary depending on the payment method selected.

Are there any transfer limits?

Before you can withdraw any funds from your account, you’ll need to achieve a higher verification level by providing your name, birth date and a trading password. This takes you to verification level one and a 24-hour withdrawal limit of 2 BTC.

By then providing your country of residence, address and mobile number, you can access a higher withdrawal limit.

Is Bit-Z safe to use?

As mentioned, you’ll need to complete account verification before you’re able to withdraw any funds from Bit-Z. The platform also supports two-factor authentication through Google Authenticator, providing extra security for the funds in your account.

Bit-Z claims to use bank-level SSL technology to ensure the security of transactions. You can also establish a trading password on your account. This code must be different than your login password and will need to be entered to confirm each trade.
