Why does the USDC fee on Arbitrum One change?

The on-chain figure is a USDT transfer ≈ 150,000 gas × current gas price, read from Arbitrum public RPC eth_gasPrice (L1 share approximated). It moves for two reasons: the network's fee market (gas, energy or priority price) rises and falls with demand, and the USD figure follows the ETH price ($2,652 when this page was built). We re-read both every 90 seconds and never fill a gap with an old number.

What is the minimum USDC withdrawal on Arbitrum One?

Right now: Binance 3 USDC, HTX 0.5 USDC and KuCoin 5 USDC. Below the minimum the exchange refuses the withdrawal; at or just above it the flat fee is a large share of what arrives ($0.200 of a 3 USDC withdrawal at Binance).

Which is cheaper for USDC, TRC20 or ERC20?

One of the two chain readings is unavailable right now, so no comparison is shown. Typically TRC20 is the cheaper of the two by a wide margin; the live figures are on the Tron and Ethereum pages linked below.
