If you buy crypto currencies in one country and then travel to another country, as long as I have the passphrase and private key on paper, hidden in mulptiple places and the crypto on an online exchange, no kyc, p2p bought, non custodial and bought on a clean laptop, can I delete the website from by laptop, including the online wallet, and then sign in again to that exchange after travelling.
I have heard, dont know if it is true, but better safe than sorry, that they now have devices to scan your smartphone and laptop to see what is on it. I would not be surprised if they do that now, the governments of the world are becoming very anti crypto currency, especially for privacy coins.
I think yes you're safe just make sure you have it all writen correctly.
And I think it is better to have a hardware wallet than an online wallet or paper wallet for me it is the best wallet to secure your crypto.
I also like the idea of crypto and travelling since we just need to know where to exchange our crypto into Fiat.
That is the benefits of a hardware wallet because we do not need to install the wallet on our laptop or mobile phone. If we want to access the wallet, we can plug the wallet into the devices we want and transact directly.
But I think he can install Binance apps on his mobile phone and don't send any coins to his wallet. He can send the coins into his Binance account wallet and sell them using the P2P market. I think that can help him get the money sent into his bank account to get a local seller from the country he visited.
