How should I proceed if I want to send some Tez to a friend without revealing my balance?
An approach could be to deposit a larger sum to a well-known exchange and then to withdraw part of it to the address of my friend (depositing the exact sum would be too obvious with an explorer). This would cost me the withdrawal fees and the coins would not be in my custody for a short time (therefore needing to trust the exchange).
Is there a safer way at the moment?
