For long‑term dividend investors outside the US, how do you calculate the true, all‑in yearly cost of holding a US stock on Binance (USDT→USDC conversion, platform fee/spread, 30% withholding, FX spread, ADR/other fees) and decide whether it’s actually cheaper or more convenient than using a traditional stock broker with treaty tax rates?

I’d really like to see how experienced investors and tax‑savvy traders build this comparison in practice, not just rely on “zero commission” marketing. #MyStocksQuestion
