What a wonderful bunch of BS on that site:
Got to love how they say that other cold wallets are vulnerable to hackers because the keys are stored online. I can already see the billboards:
Online cold storage solutions with hackable private key features. Who can say no to that?
At the same time, their answer is offline key storage, but there is a web-based app that is part of the mixture somehow.
Isn't that Electrum was one of the cold wallet? I had been used this for a couple of years and yet from that period of time
up to now, I had never been encounter such an issues like hacking or what? And for the op story about the paper wallet, where not so sure if this paper wallet has been return to the original owner. And if ever She found the real owner, how is that happen? since the address in the bitcoin indicated in the paper wallet was anonymous?
