I've seen one site so far which offers the ability to watch a wallet, and tie into your api of your exchange,
You sell one BTC it uses your exchange Fiat balance to buy 1 btc. etc.
Well,too many confusions right here.You mean you have a watch only wallet on a third party site ? Dissolves the point of a "watch only wallet".Why not just keep the balance in your trading account instead ? Sorry I'm having troubles to understand the second part."Exchange Fiat Balance" ? How can you have fiat on an exchange?
Is anyone else working on this? the cost was pretty high for what to me seems like a pretty straight forward script/setup.
Not as straight forward as it seems.
Yes i understand server space/security/etc...
Doesn't stop there,..Escrow,2FA,automation and it goes on..I could give you clarifications if you elaborate .
