Crypto Taxes

If I buy BTC on a exchange A in country X, then transfer it to a cold wallet, then transfer from my cold wallet to an exchange B in another country (this country Y, I do not have to pay taxes if I convert BTC to Fiat currency up to USD 10k per day), then I buy USDT 10k on the same exchange B, then I send it my cold wallet, then I send USDT to back to exchange C in country A, then I convert USDT to fiat currency. Do I have to pay taxes in country X?
