I would know if it is possible to send BTC without a transaction fee regardless of theoretically or practicall..
Are you serious?It seems like you want to buy an item from a grocery store that is tax exempted huh?
Will never happen buddy that is more than impossible to become reality
Not unless youre a senior citizen, you can ask for some discount but in cryptoworld, transaction fees is everything. Honestly, there are some new exchange site who started with transaction free but in the long run they make a new rules that they will going to start collecting fees, so this mean at the end of the day, you still need to pay the fees.
