Cryptocurrency fees comparison

I am new in this world of cryptocurrency and trading, so my first sight was to accept that fees for withdrawals were normal and thought that all exchangers had the same fees, a little bit naive, but after watching some videos of people trading in different exchangers I realise that fees rate were different, so I made a little research of some coins that are well know and common in the ones that I know, of course there are a lot of exchangers and more coins but these is what I found out.

I hope this be helpful in any way.
