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 ?
The only way that you can do to convert it into another coin that has better scalability. Im always converting my ethereum to the binance coin to get the low fees. You can do nothing about that as the fees will be determined by the network itself. It's better waiting for the traffic to go down before trying to create a transaction.
