Hello everyone,

Im in a bit of a dilema here.  Let me jump right in.
Here is my problem.

Lets say, I received 3 payments from 3 different people. (lets call them A, B, C)

Mr A paid me 0.5 BTC (unconfirmed)
Mr B paid  me 1 BTC  (2 confirmations)
Mr c paid me 1.5 BTC (5 confirmations)

And so, in total i had 3 BTC on my blockchain.info wallet.
I then sent 3BTC to shapeshift to convert to a Alt Coin (i wont say which lol).

Now this is where the problem starts...

The 3BTC payment is forever pending on shapeshift's address because of the unconfirmed 0.5btc sent from Mr A (because Mr A sent the 0.5 BTC to me with a miners fee of 0.0002 BTC).

Lets say this 0.5BTC is not confirmed in x amount of time. Im assuming, the 0.5BTC payment goes back to Mr A. What happens to the remaining 2.5 BTC ?

Does it

- Go on forward and get confirmed on shapeshifts address (destination) ?
or
- Come back on my blockchain.info address (origin) ?

Can someone please clear this up.

I personally blame blockchain.info for allowing unconfirmed transactions to be included in available balances and then allowing users to send out balances that contain unconfirmed transactions within it. This causes payments to be choked further along the line.  

PS. Whats even more wierd is this transaction ONLY shows on blockchain.info's blockchain explorer. On the other blockchain explorers, it doesnt even show.
