Trust me if you want. $2 is chump change to be fair but it's a lot of effort to get cash into Bitcoin especially for such a small amount. Don't ask me for collateral. If I had something, I would've sold it.
Here's a small exchange I did a short time ago:

You say yourself, you have no collateral, so the reply is simply no loan for you, please lock this topic yourself and come back if you can offer some collateral.
