Keep in mind that when you are going to buy Bitcoin with your card, you have to undergo verification, so you need to provide your identity. Also, there will be a charge for your purchase. I think a more easy option for you is to make a P2P purchase. So you can avoid a lot of hassle when buying Bitcoin. Even you can seek on the forum Currency Exchange section to purchase Bitcoin by cash. Just make sure the seller is trusted; otherwise, use an escrow service. So you are safe.
I don't know why, but I don't trust negative trust users, even with escrow. And I think that most will have the same attitude. Appearing on a forum after a long time to seem interested in buying Bitcoin, yeah, he might find some weirdo who will believe him and exchange first. Look at the OP's tags; the system works great.
