I just wanted to share with you a website that I found in the internet. This website has a clear lay-out and gives information about the all time high prices of all the coins. It also give the ATH day and how long it was ago. Besides this is lists the current price and give the % of the current price compared with the ATH.
I didn't know this site and it isn't mine but I will add it to my favorites cause for me it has useful information.
The website can be found here: https://athcoinindex.com/
Cheers,
Peter
