So long story short, I sent some crypto (LTC) to a bitcoin wallet address (Coinbase). A random LTC address was generated that relates to the BTC address that I originally sent it to, and is where the LTC is now. I have no way to access this LTC address, as it doesn't exist.
The place that I sent the coins from says they can't help.
Coinbase says they have no private key information and the coins are lost.
This was $300, and while it won't kill me, its just annoying at least because I know there is a way to access that address using a private key. If anyone is willing to help me I would really appreciate it.
