The other day I received my first payment

tnx
I'm wondering if an option will be added that we can ask for the amount of
BTC we want to withdraw?
For example I want to withdraw
BTC on my cryptopay wallet, but they do not have the last 4 digits, and if I have on my PotionCoin acc 49 999 satoshi and I withdraw to my wallet I will only receive 40 000 satoshi.
Hello,
An option to choose if you want to withdraw your balance and specify the amount you want to withdraw is in construction for some time. It will be available soon on Profile page.
Regarding cryptopay, you can change to another wallet.
