Not joking, explain the difference between me subscribing to a magazine and mailing a check, and your 0-confirm transactions. Penny Stock Weekly won't be able to spend the check I sent them until it clears, your trading partner won't be able to spend the unconfirmed transaction. Where's the difference?
So you're saying the following: - Double-spending a TX is easy and can be done by anyone
- It takes the same amount of time for a unconfirmed TX to get confirmed as it takes a check to be cleared.
I'm asking you to explain the difference between an unconfirmed transaction and a check in the mail (which hasn't cleared). I can rephrase the question again, if you wish.
To put this back in context:
Wrong. Transaction time is: ~1-3 seconds. Confirmation time is: ~10 Minutes.
Dropping a check in the mail is ~1-3 seconds too. Of course, the recipient won't be able to spend the money until the check clears, but that's no different from your unconfirmed transaction.Update:
plz no!!
