I too joined and they had adsense up an running right away, think that might help cover some costs, have withdrawn successfully just from my free mine though.
it might be a good idea to get a xapo wallet, it seems secure, you can have multiple addresses, although for trading you would have to send manually to an exchange(some if verified can send funds right to bank accounts) or similar to exchange to any currency, although they are starting a debit card program might also be worth looking into. I wonder if others think xapo is safe place to store btc online ?
