your btc won't be delivered unless you pay a fee. 0.0028 btc is too much but your transaction will be returned after some time if you don't pay a fee.
Is sending only 0.00001 btc enough instead of the dynamic fee of 0.0028 btc?
This really depends on the memory pool, when it is/ would be almost empty, you could get a confirm within 1-3 days.
Unfortunately for you, it is currently absurdly high, there's a backlog of over 200k transactions i believe. See
