How to Convert Crypto to Cash on Polygon (2026)

I tried to cash out Bitcoin once. The KYC took days, the fees were painful, and some of it still hasn’t arrived. Polygon solves all three of those problems. Here’s the actual process for converting crypto to cash in 2026.

Before I started building on Polygon, I tested the process of converting cryptocurrency to cash using Bitcoin. It was frustrating in ways I didn’t expect. The identity verification took days. The fees compounded at every step. Some of the funds still haven’t arrived in my account.

That experience is part of why I chose Polygon for RizeCoin. The three barriers I hit with Bitcoin — KYC delays, high fees, and slow settlement — are all significantly reduced on Polygon. The process of converting Polygon assets to cash is the same in structure, but faster and cheaper at every step.

The Three Barriers I Hit with Bitcoin

What actually happened when I tried to cash out BTC:

KYC verification: Before I could withdraw fiat, the exchange required identity verification. Photo ID, selfie, proof of address. The process took days and required multiple re-submissions. You cannot skip this step on any regulated exchange — it’s a legal requirement.

Fees at every step: Network fees to move BTC. Exchange conversion fees. Withdrawal fees to the bank. Each step took a cut. The amount that arrived was noticeably less than what I started with.

Settlement time: Bitcoin transactions can take minutes to hours depending on network congestion. Bank settlements add another 1-3 business days. Some transfers I made still haven’t fully settled.

Polygon doesn’t eliminate all of these barriers. But it reduces the fee and speed problem significantly.

Why Polygon Is Different

Polygon transactions confirm in seconds and cost fractions of a cent. Moving USDC or POL from your wallet to an exchange takes minutes, not hours. The fee issue doesn’t disappear entirely — exchanges still charge withdrawal fees — but the on-chain portion of the process is fast and cheap.

The KYC requirement doesn’t change. Any regulated exchange that allows fiat withdrawal requires identity verification. This is the one step that takes time regardless of which blockchain you use.

Before You Start

What you need:

1. A MEXC account with KYC verification completed. This is the step that takes the most time — start early.
2. Your bank account details for fiat withdrawal.
3. POL or USDC in your MetaMask wallet on Polygon Mainnet.

KYC on MEXC typically requires a government-issued ID and a selfie. Approval usually takes minutes to hours, but can take longer depending on your region. Complete this before you need to withdraw.

Step 1 — Send Your Tokens to MEXC

Open MEXC and go to your wallet. Find the deposit address for the token you want to sell — POL or USDC — and make sure you select the Polygon network.

⚠️ Always verify the network before sending.

MEXC supports multiple networks for the same token. USDC exists on Polygon, Ethereum, and other networks. If you send Polygon USDC to an Ethereum USDC deposit address, your funds may be lost. Always select “Polygon” or “Polygon PoS” as the network when depositing from MetaMask.

How to send from MetaMask to MEXC:

1. Copy your MEXC deposit address for the token and network
2. Open MetaMask on Polygon Mainnet
3. Click Send and paste the MEXC deposit address
4. Confirm the transaction
5. Wait for confirmation — on Polygon this takes seconds
6. Check your MEXC wallet — funds should appear within minutes

Step 2 — Sell Your Crypto on MEXC

Once your tokens appear in your MEXC wallet, you can sell them for fiat currency.

For POL:
Go to the Spot trading section. Search for POL/USDT. Place a market order to sell your POL for USDT immediately at the current price.

For USDC:
USDC is already a stablecoin worth $1. You can convert it directly to your local fiat currency through MEXC’s convert feature or sell it on the P2P marketplace.

Step 3 — Withdraw Fiat to Your Bank

After selling, go to MEXC’s withdrawal section and select fiat withdrawal. Enter your bank account details and the amount you want to withdraw.

What to expect:

Withdrawal fees: MEXC charges a fee for fiat withdrawal. The amount varies by currency and withdrawal method. Check the current fee schedule before confirming.

Processing time: Bank transfers typically take 1-3 business days after MEXC processes the withdrawal. This is the banking system’s timeline, not Polygon’s.

Minimum withdrawal: There is a minimum withdrawal amount. Small amounts may not be worth the withdrawal fee.

The blockchain part of this process — moving tokens from MetaMask to MEXC — takes minutes on Polygon. The part that takes days is the traditional banking system. This is where Polygon’s speed advantage ends. The fiat system moves at its own pace.

USDC vs POL: Which Is Easier to Cash Out

USDC:
Already pegged to $1. No price risk during the conversion process. Easiest to convert to fiat because the value is stable and predictable.

POL:
Price fluctuates. If you sell POL for fiat, you’re also making a decision about when to sell based on the current price. More steps involved — sell POL for USDT first, then convert to fiat.
