Coinbase has a recurring buy option from your bank account. You could setup a US bank acct and have your US employer direct deposit into that account. Then setup your recurring buy from coinbase to trigger after pay day. Your cost will be 1%.
Does that really work? Can you really fund your account from any bank account, even if it's not your own? That would be fantastic.
You can fund from any bank account as long as you have the routing and account number (so yes). I think this would be the easiest way for you if direct payment in BTC from your employer is too difficult, and the amount is a consistent (recurring) amount.
