Withdrawal fee shouldn't be an issue if the complainer make use of the alternative crypto which was implemented by the Roobet admin as the solution to the possible high fee of Bitcoin and Ethereum which will always happen during the bullish market.
Therefore, she has to accept that the mistake is from her end.
I have an experience to withdraw my profit from Roobet.com, and just for once. I never withdraw anymore, when I use standard fee the speed of transaction just for an hour and I looked at my balance, it only decreases according to how much I withdraw even the transaction fee count is left in the balance. Did I see wrong at the time?
If you are saying that you received less funds from the actual amount with withdrew then the amount missing is supposed to the transaction fee collected by Roobet because standard mode doesn't mean that its free withdrawal.
