Quick Summary
Most people don’t think about this when they hold USDC on an exchange. The coins are held on their behalf, as the exchange controls the private keys. Gem Wallet works differently. When you buy USDC, it goes directly into your self-custody wallet, where you retain control of your assets.

USDC – The World’s Second-Largest Stablecoin
USDC (USD Coin) is a stablecoin pegged to the US dollar at a 1:1 ratio. It was created in 2018 by Circle and Coinbase to provide a more stable way to use digital assets without the volatility typically associated with cryptocurrencies.
Each token is backed by reserves consisting of US dollars and short-term US Treasury bonds. These reserves are held at regulated financial institutions, including BNY Mellon, and are subject to regular independent attestations by firms such as Grant Thornton.
USDC is currently the second-largest stablecoin globally, with approximately $78 billion in circulation. It operates across multiple blockchains, including Ethereum, Solana, Base, Arbitrum, BNB Chain, and Tron, and is widely used in decentralized finance (DeFi), payments, and cross-border transactions.
A stablecoin is a type of cryptocurrency designed to maintain a stable value by being linked to an underlying asset, most commonly the US dollar.
How to Buy USDC: Exchange, Wallet, or Fintech App
There are several ways to buy USDC, and the method you choose determines how your assets are held.
Crypto Exchanges (CEX)
A common approach involves registering on platforms such as Binance or Coinbase, completing identity verification, and purchasing USDC. In this case, the exchange typically holds the private keys on your behalf. While convenient, this means access to funds depends on the platform’s security and policies.
Crypto Wallets
Some wallets allow users to purchase USDC directly within the app. It is important to distinguish between custodial and non-custodial wallets. In a self-custody wallet, private keys are generated and stored on the user’s device, allowing full control over assets.
Fintech Apps
Fintech platforms offer a simple way to gain exposure to USDC. However, in many cases, users do not hold the actual tokens but rather a balance within the app, and withdrawals to external wallets may be limited.
Why Buy USDC?
USDC is used for a range of practical applications:
- Hedging volatility: Users may convert assets into USDC during market fluctuations without moving funds back to a bank account.
- Cross-border transfers: Transactions can be completed within minutes at relatively low cost compared to traditional banking systems.
- Earning yield in DeFi: Platforms such as Aave allow users to supply USDC and potentially earn interest, subject to protocol risks.
- Liquidity on demand: Funds held in USDC can be quickly deployed into other digital assets when opportunities arise.
- Access to digital markets: USDC can be used as a base asset to access a wide range of tokens.
- Payments: It is increasingly used for freelance payments and international transactions where traditional banking access is limited.
