Hello I want to know if The Withdrawal fee of Poloniex is really 0.00010? For example if I withdraw my 100ksat I will receive 90ksats? right?
Yes, if my memory is correct, the withdrawal fee of Poloniex is still 0.0001 for BTC.
A 100k sat withdrawal will leave you 90k sat. I cannot remember there is another exchange still having this level of low BTC withdrawal fee.
