Hello everyone!

I am thinking about sending some BTC from my Electrum Wallet. Dynamic fee option is enabled.

Previews of transactions fees: 0,0017 BTC in 5 blocks, 0,0016 in 10 blocks, 0,00007 in 25 blocks, roughly.

My questions:

1: It seems to me transaction fees for "within 5 blocks" and "within 10 blocks" are very high. What do you think? Are these fees normal & usual these days when sending BTC's?

2: How long it will roughly take my BTC to arrive if I choose "within 25 blocks"? Do you think it is safe & reasonable to use it?

EDIT:

I have noticed that when number of sending addresses increase, fees also increase... This explains why fees so high for me.
