I noticed that transaction fee for below $50 Bitcoin is higher that its core amount? what is the reason ?
How much did you paid for? Base on
https://bitcoinfees.earn.com/ the fee is only 30 sat/byte unlike before that it was higher than multiplying it four times.
There's a website that shows even lower fee but I forgot about it.
You possibly paid for the high priority fee and that's why you found it expensive.
There's no spam to the network so basically the fees are calm now and its very cheap to send bitcoin and its quicker than before.
