ive never done a mempool transfer.
Unfortunately, the fees are currently a bit high, so if you are not in a hurry, waiting for several days may reduce the fees a lot.
Go to this site --->
https://mempool.space/ when the fees are in the 5 sat/vB to 50 sat/vB then they will be low on average.
if someone was trying to move $200 worth of BTC 0.005 at the moment which would they choose?
We cannot give you an exact answer unless we know more information such as number of inputs, number of inpouts and the type of addresses in the transaction you want to create.
