Ok Ok, its mean I got the right meaning of it, I got confused when I read that line for the very first time so I ignore it but when you quoted it again I thought it must meant something so I searched it and found out that it represents non serious mode (sarcasm). Well thanks for mentioning it, new word added to my dictionary (after all I am a logophile

)
I was also going to mention it as we can use paper wallet to but I avoid it, it is so difficult for me to carry or safe a paper wallet, I don't have any someplace in my home where I can keep it away from others hand. And there are other reasons too so I avoid it but a air gapped wallet can do the work instead.
And to be honest, after the last leak of ledger customer's database with full home addresses I would also not be that thrilled to buy something from an online shop.
I was not aware from this news, thanks for bringing it in front of me too. I will look into it more.
