and where the heck did over 2000$ of my coins go!?!?!?!?
Whoah ...
InstaWallet at one point in time preferred the term "low security wallet" to describe what service they offer.
That's because these Instawallets don't have security features that other EWallets offer, including username and password (for low value storage) and two-factor authentication (for when amounts stored will be of greater value).
With InstaWallet, all you need is the URL and you can spend the funds. That makes it essentially a "bearer instrument", just like the cash in your pocket -- spendable by whomever has physical possession.
I'm not sure why you'ld send from one Instawallet to another, but but hopefully both were ones that you created and nobody else has access to the URL.
Just as a sanity check, look up your destination wallet and make sure the Bitcoin address for that matches exactly the Bitcoin address that you sent payment to.
its been over 7 confirmations too..
That should be enough for it to be credited. I'm not sure there is anything anyone here can do to help you.
