If I transfer .002 BTC from Coinbase to Ledger the fee is around $2.20. If I transfer the exact same amount of BTC .002 back to Coinbase from Ledger at the same time the fee is $16.50....
When did you transferred 0.002 BTC from Coinbase to Ledger?
When did you transferred 0.002 BTC from Ledger to Coinbase?
How long between two transactions? If it is long, mempool can be changed and fee will be higher or lower.
Maybe you only post an example but if you transfer 0.002 BTC from Coinbase, you will be charged fee and you will not receive 0.002 BTC in Ledger.
Why are the fees so drastically different? Why is Ledger "charging" so much more... I found the fees similar and high for Trezor wallet too.
Depends on their fee esitmator that can be correct or inaccurate.
You can check the mempool:
