I look at your website and discover that if I scroll down, more charts for more cryptocurrencies will appear. It is like non stop as if I scroll down more, more charts will be loaded.
My suggestion for you is to set up a default total charts on one page, like 5 or 10 charts, if people want more, click on page 2, 3 and next. It is for random chart list from your site or from customized chart list for a registered account.
