When can I start trading? I just started

So when can I start trading? I tried it once and it said that my account had to be active for 24 hours. So does that mean 24 hours play time, or just 24 hours since I started (offline counted as well)?

And 1 other question: What is a B-Cake?
I assume that it's the Birthday Cupcake, but I'm new so I could be wrong. It seems a bit weird that people are willing to pay 100g+ for an item that drops so often.

Idk when.

Wiki is your friend type /wiki birthday cupcake

It will tell you that it basically drops once a year for a week. This yr 2 weeks.
Some peope are paying more than 100g for them cuz later they go for much more BUT this year with diablo 3 and guild wars 2 around the corner and the extended event, prices are down.

Your account must be 24 hours old before you can trade with others. That is 24 hours from the moment you created the account. This is counted in real time, so yes, offline time counts as well.

Awesome. Thank you to both of you for the swift replies.

Two things:
- 100g may seem like a lot when you first start out, but it's really not much.
- people use lots of sweets, like Cupcakes, to get their Sweettooth title, so there's a lot of demand for them.

cupcakes usualy are ~700g each, exept at events when they drop...

I'm wondering with GW2 looming how much they will go back up in price... I'm still saving mine to sell later...

wouldn't be surprised if they go up higher as normal years

Cupcakes are powerful Buff too, God I luv'm; I've got 42 and I wont be selling any of mine.
Unofficial personal obersvation; but I've seen the most B-Cake drops in the Underworld.
