$USDC 1. How to earn from price differences (retail arbitrage):

• Buy USDT/USDC at a low price from one source (for example, someone who needs to sell quickly, or an exchange with a low price).

• Sell at a higher price to someone who needs to buy urgently (or another exchange with a higher price).

• Make a profit from each transaction ranging from a few hundred to several million depending on the capital.

Example: Buy USDT at 24,700 – sell at 24,900, profit 200/1 USDT. If you trade 1,000 USDT => profit 200k.

2. Risks to be aware of:

- Slow liquidity: Unable to sell in time, price reversal means loss.

- Blockchain fees: Transferring TRC20, ERC20 wallets… incurs fees (ERC20 can be quite high).

- Scam: Peer-to-peer transactions can be easily deceived, especially if you're not familiar.

- Market volatility: Stablecoins are not always 100% stable, there have been times of depegging.

3. How to optimize?

• Find reputable sources to buy at good prices. (Many private groups or sometimes P2P Binance can be cheaper).

• Rotate capital quickly, avoid holding for too long. Make small but continuous and regular trades.

• Use wallets/exchanges with low fees. TRC20 is perfect for small capital, while ERC20 is for larger plays.

• Take advantage of hourly/daily fluctuations: Prices tend to vary more late at night or on weekends.

Honest opinion:

This method can make money, but:

✅ the larger the capital => the more profit from differences, as fees are almost fixed.

✅ liquidity and reputation are extremely important. Retail trading can still be deceived if complacent.

✅ you must closely monitor the market, be sensitive to opportunities.

-> To be direct: This method is good to start, learn how to trade, sharpen financial reflexes, but to earn big – and sustain profits, you need to expand your sourcing, loyal customers, or build your own network.
