Im new to this whole bitcoin world and I have some questions.
Can you have a wallet on your iPad?
How many posts do you need to have before you can trade things in the marketplace forum?
5 post and 4 hours of logged in (browsing) time.
Then, make a post in the whitelisted thread to be whitelisted to the other sections.
What is the best exchange to buy and sell on?
I would say Mt.Gox as it's fairly decent for USD trades (as it's one of the most active), but Tradehill is a good second. Also, is good if you want to decentralize (keep your eyes open for others).
