its impossible to trace the person or bank by wallet address either??

99.999% impossible though, that fraction of chance is only if you trace the funds and if it entered into some exchange and you found exchange then you contacted them and they gave you the identity but its close to impossible.

that is possible when scammers use an exchange wallet, it can be tracked where the landing place is by the exchange address name.

Unlikely.

There's no information that's being made for each wallet address so it's just wallet address to another wallet address so if you're asking about tracing the person's bank account or himself, it won't happen.

so its impossible to track or trace by cryptos scam??
