Tomorrow 1BTC will be valued at 1.05*(1BTC

That's not possible.

Hi shinyshiny! My brother introduced me to bitcoin!

What? I don't understand, if your PC isn't secure then you will lose your Bitcoins, online or offline.

EDIT: I've lost 2 BTC on my coinbase wallet because I was phished (password reuse, I use ubuntu), this wouldn't have happened if I had an offline wallet. So it's even less secure in some ways.

It's probably just a never ending image. It's quite clever, I thought it was javascript at first!

Are you willing to escrow this trade? Nice account by the way.

Why do you want to use an offline wallet? A desktop wallet is more secure and does not require trust.

I'm new too! I don't think the group buys are a good idea through, you'll have to trust someone else and there's no promise that it will be profitable!
