Weird, so what happened to the coins then? what does the blockchain say?
I told the person to use Unstoppable wallet because it was an altcoin, he import the seed phrase and he saw the coins.
Some people will later see the coin on Cake but to spend it will be difficult.
They also claim a technology to anonymize Bitcoin transactions called "Silent Payments" as well as "Payjoin". How does this work?
In payjoin the sender and the receiver both contributes input instead of only the sender to contribute the input. It is good but its anonymity is better on coinjoin.
Silent payment the address is like this: sp1qqv9cans0yhetnl34e7zxxp8wq0crpk7xgv23efuw6jv8yur9jvvyuq4xv37x3879xuedyfq30f4

It is like a public key because anyone you send it to can use it to send bitcoin to you at different times without sending the bitcoin to the same address but to different address each time.
