it was proved that the COLD wallet can be hacked. once you are hacked, you cannot recover the bitcoin.
Yup, and normal people can easily pick up a handful of moondust, provided NASA takes them to the moon first.
or they can think : why would I use Bitcoin when I have fiat currency and other payment processors?
Yes, I can use Bitcoin to speculate a bubble but nothing more.
Or, I can use Bitcoin just because I can, without making some old fat fart very reach for processing my Western Union transfer and taking tons of money as a fee for transferring some bytes of data over the internet.
Stop being so stubborn. I just bought 2 Steam Gift Cards with Bitcoin, just because I can, and I'm not giving my credit card information or personal information all over the internet for some small thing like those.
YOU on the other hand are the one using Bitcoin just to speculate, right now you're also very angry cause you're not rich already.
You should try using Bitcoin, it feels nice.
