In recent days, the ether network simply does not work, and if it works it costs a very large commission, so I just do not use it for the last three days. Let's hope that Vitalik Buterin can do anything with this
That is the huge challenge for eth platform if there so many user accessing the trading platform, transaction are completed longer than its normal time and every transaction has a fee even cancelling order therevis a fee i hope this can be remove someday since cancelling order doesn't give you any profit doesn't make sense if you chsrge it for transaction fee.
