I don't know if it is sure and safe but supposedly i pay and not pay such cosmic commissions as you are now. How can i do this ?
If you need to send tokens based on Ether from your wallet, then you have no choice but to use its network. Just wait for the night, usually at this time most traders are asleep and the cost of gas falls slightly. If tokens or coins are on the exchange, it may make sense to consider selling tokens for those coins whose network commissions are not so high.
