You really don't need to look any further than this table:
The promise here is that if you invest $10k into Dunemining today, after 3 years, you'll receive $54k in return. Essentially a 440% net profit. That is completely unsustainable and a telltale sign that they are either a ponzi, or just some random scammer on the internet posing as someone knowledgeable about crypto mining to lure in investors, before pulling an exact scam.
The correlation between this site and veritas mining doesn't really matter. Plagiarism is something that is expected of ponzi scammers that have no intention of starting their own business model. Not to mention the fact that Dunemining lies about their partnerships with Nicehash, bitmain, antpool etc. It's certain that they are a scam, not even an "extreme chance".
