On the fiat-to-XMR question: the safest no-KYC route for a beginner is usually a non-custodial swap service — you send fiat (or BTC/ETH bought elsewhere) and it sends XMR straight to your wallet address, with no account needed. Fees are typically a few percent, and it's wise to do a small test swap first before moving larger amounts. For wallets, Cake Wallet on mobile and the official Monero GUI on desktop are the standard safe picks — just write the 25-word seed down on paper and never share it with anyone. And on KYC'd XMR: there's no 'taint' flag on the coins themselves, but the exchange knows the address it sent to, so use a fresh subaddress per purpose and keep KYC-sourced funds in a separate wallet if you want clean separation.
