You are right about litecoin, but Ethereum transaction fee is also high, litecoin can help reduce the much delay in payment confirmation. For me it would be better he pays with usdt-trc20 this another cheapest means to send out payment maybe after 1-3 weeks when the network congestion may have reduced then he could start paying back with bitcoin as usual I think this suggestions has been made before we don't need to stress over this anymore I believe the manager knows what to do at this moment. The only thing it would cost him is just to moved the topic to altcoin service section, maybe when we gets back to Bitcoin he may then move it back to where it's now.
Ethereum token transaction can be very high but ethereum transaction is not high. You can try and use ethereum to make transaction and see that it is not that high. But litecoin transaction is far more lower than ethereum transaction.
And even now, the mempool congestion is going down.
This is the current state of the mempool. So probably your next week pay, everything might stabilized. I wish you guys all the best.
This is just about luck. The day after halving it is fell to 75 sat/vbyte but I saw it over 200 sat/vbyte the following day. Let us expect it to drop and see what will happen.
I am still surprised that most of you people do not want to use lightning network. Or just accept biweekly pay.
