btcmarkets.net is not possible with € , right?
So I need a bank account that can deal with $?
You should add this to the "Please only apply if you have:".
And also there is the risk of fraudulent payments to your bank account from users. This is very risky because you can loose money and bank account.
Is there anything that btcmarkets does to prevent this?
Thats right. You need an Australian Bank Account to make withdraws and deposits. To transfer money between AUS Bank Acc and EUR Bank Acc you can use Currencyfair or Transferwise. I will add it to the list.
There is no risk for fraudulent payments cause both platforms only deal with deposited money. No direct bank transfer between users.
And to avoid the risk of bitcoin price drop/raise we just use the nice leverage system of kraken
