Coinbase.
Virwox or Coinsbank, They're better than coinbase right now.
Coinbase.
Fuck coinbase! Coinbase is a legit scammer. They will just scam your funds there. Use localbitcoins.com instead. So far it is more reliable exchange with alot of payment options. If theres available local wallet in your country much better. You can buy through there. Me, im using local wallet and they got a lot of way to buy bitcoin. Just find one.
Coinbase will be dead soon, A lot of troubles were using coinbase, There is a rumour if they were getting hack in the past week ago.
