That's quite a statement, so I got curious:
Enjin.io doesn't give much information, but shows mostly cool-looking pictures and an instant "Download Now" link and a signup link without saying what it really is. The entire website screams "ICO", and indeed, they raised tens of millions of dollars at the peak of the ICO-hype.
So who are those "People" who "say that Enjin is like hardware wallet in phone"? It's Enin themselves! Please don't post marketing slogans as if it's true.
But wait, they also have Proven Security, including "An extensive independent security audit and penetration test found no security issues". So what does the Report say:
Now read that again, because that's where I stopped reading the report! In short: If your device is secure, you're good to go. That's nothing like a hardware wallet, which is supposed to protect you from software threats.
