How is 1 USD gonna help you, why are you not buying bitcoin if you are interested on it?
You don't get any satoshi without collateral, since you just made an account and now you ask for 1 USD. Everyone would do that if they got a free dollar everytime.
Im pretty sure you already know what bitcoin is, and what you can do with it since you started to beg on the first post that you came here.
Lock your thread, since you are wasting our time and your time, no matter how many new accounts you make, you won't still get a dime.
