I had sent it sent directly to coinbase.com exchange, because I had plans to converting it to SOL. I'll never make that mistake again.

Since I sent it directly to coinbase.com and they own those private keys, would it be possible that coinbase is leveraging my hash with high rate fee to get other low rate fee hashes confirmed?

This is the hash id b5411a3c59d1472b5627b423355564cc26fc1345fee435f0665299f637c1d286

I checked the accelerating fee and it would cost me $3,000, which is over 3x the amount that I sent to coinbase.com exchange. So basically there is not I can do, but to wait or it gets purged from mempool.
