The fast confirmation fee right now is 0.2 sat/vbyte but mempool.space is showing 2 to 3 sat/vbyte which is not true.
Mempool.space is only showing
estimated fees, and fees can quickly change at any time.
I am just looking at their website now and I can clearly see fees shown bellow 1 sat/vbyte, but you can always run mempool.space with your own bitcoin node, if you don't trust them.
You can also use several different sources to compare estimated fees, for example whatthefee.io or bitref.com
