How to Cash Out the Cryptocurrency You Earned
Earn cryptocurrency tokens by playing games or engaging in Web3 projects.
Wait for the token you’ve earned to become available on a cryptocurrency exchange.
Transfer your tokens to an exchange that supports the trading of that token.
Sell or trade the tokens for a widely used cryptocurrency, such as USDT.
Send the converted cryptocurrency to a local exchange operating in your region.
Convert the crypto into your local currency through the domestic exchange.
Withdraw the funds from the local exchange to your personal bank account.
Cryptocurrency tokens earned through Play-to-Earn games or Web3 apps may not always be directly listed on exchanges available in your country.

How can I withdraw the cryptocurrency I earned?

In many cases, tokens are listed only on international exchanges, so opening an account with a foreign cryptocurrency exchange is often necessary to cash out.

I see! Since earned cryptocurrency tokens may be listed unexpectedly, it’s wise to open an account in advance for a smooth cash-out process.
