Getting your earnings out of PolyGram is simple — since your USDC sits on the Polygon network, you have several convenient pathways to convert it to fiat currency or move it elsewhere. We'll walk you through each option.

Understanding Your USDC Balance

Once your prediction market bets settle in your favour, USDC is deposited directly into your PolyGram account on Polygon. From there, your choices include:

  • Continue participating in markets using the same funds
  • Send it to your own cryptocurrency wallet
  • Move it to a major exchange and convert to traditional currency
  • Utilise PolyGram's direct fiat conversion service for immediate bank deposits

Method 1: Fiat Off-Ramp (Bank Transfer)

The simplest choice for those new to crypto:

  1. Go to Wallet → Withdraw within PolyGram
  2. Choose "Bank Transfer" or "Fiat Off-Ramp"
  3. Input your banking information (IBAN for European accounts, routing and account number for US accounts)
  4. Specify your desired amount in USD/EUR/GBP
  5. Your money arrives within 1-3 business days

Fees: Approximately 1-2% for currency conversion, plus any charges your bank may apply

Method 2: Withdraw to Crypto Exchange

Ideal if you want competitive rates when converting to traditional money:

  1. Locate your Polygon USDC receiving address on your chosen exchange (Coinbase, Kraken, or similar)
  2. Within PolyGram, select Wallet → Withdraw → Crypto Withdrawal
  3. Paste the exchange address and confirm you're using the Polygon network
  4. Your USDC appears on the exchange in roughly 5 seconds
  5. Trade your USDC for USD/EUR on that exchange
  6. Request a bank transfer to complete the process

Fees: Minimal Polygon transaction cost (~$0.01) plus the exchange's conversion spread

Method 3: Self-Custody Wallet

Maintain complete ownership of your assets:

  1. Retrieve your Polygon wallet address from MetaMask, Trust Wallet, or a hardware device
  2. Initiate a withdrawal from PolyGram to this address
  3. Your USDC transfers in seconds — no third parties involved

Once in your personal wallet, you're free to interact with decentralised finance applications, move funds to other blockchains, or simply hold your balance.

Fastest Withdrawal Path (For Impatient Winners)

  1. PolyGram Wallet → Withdraw → Coinbase deposit address (Polygon)
  2. Arrives on Coinbase in 5 seconds
  3. Immediately convert USDC → USD on Coinbase
  4. Bank transfer completes in 1-2 business days (no fee for Coinbase One members)

FAQ

Is there a minimum withdrawal amount?
Cryptocurrency withdrawals have no floor. Fiat off-ramps typically require a minimum of $10-25, depending on which processor handles your request.
Are withdrawals taxable?
Simply removing USDC is generally not a taxable action — instead, your tax obligation arises when you win the prediction market itself (the moment you realise a profit). Seek guidance from a qualified tax adviser familiar with your local rules.
How do I know my withdrawal is secure?
Every withdrawal is recorded as a transaction on the Polygon blockchain. You can confirm any transfer's authenticity by searching Polygonscan.com with your transaction ID.
