"If BTC is placed in the electronic wallet, it also needs to pay a handling fee" no fee at all, it´s your wallet, no government can access a cryptographic wallet in YOUR custody

"If you use a cryptocurrency trading platform. The same logic as the bank. The cryptocurrency exchange closed down and took away BTC"

Never use a exchange!! use p2p transactions! store your BTC in your own wallet

Buy and sell BTC in p2p mode! dont trust, verify!
