@OP, if your claim is right, can you please share your transaction id (If you don't mind). Sharing transaction details isn't harmful if you don't have problem with your privacy. Otherwise your post value is likely ZERO as other users already mentioned. I don't think someone will seek 35$ loan who have $30K.

However just keep all suspension is side let's talk about your problem. Only coinbase is the one who could help you on that case since coinbase is a custodial wallet. But therr is very low chance to recover your fund if really you did mistake. Just try and don't give up.....
