Haven't seen any discussion about the site on Bitcointalk using Google and quotation marks to look for exact matches to Cryptodump, but from what I can see on Reddit, seems like the site's a scam.

Funnily enough, the site claims to have history dating back to 2016 based on what I can see on the site from their monthly archives, but the domain was registered on the 31st of August according to a EURid Whois lookup. Wouldn't trust the site based off this alone, and I would stay away from this site as a whole.
