In case of hitbtc i can not remember if it uses a payment id, does someone know?
Hitbtc deposits need only wallet address.
To withdraw AEON need payment id and wallet address.
Please do not try to confuse the newbies in the thread. HitBTC does not need the payment_id for deposits and withdrawals. Their wallet was set up the same as any other cryptocoin's wallets. All you need is put the amount and the public address.
Talking about HitBTC, Aeon's daily average volume is improving.
