I can pay with paypal, credit card, bank transfer or cash (if you're in berlin). I've never made a trade via this forum so I'm wary and would appreciate some advice on how to do this safely (i.e. using escrow, etc.)
Why don't you just use an exchange mate? You will get much better prices and you will be much safer than buying of the forum.
If I was you, I would use Kraken. SEPA in and out very fast and they don't ask for much verification for your amounts that you wish to buy!
