Bitcoin is good but the blockchain offers an open ledger of all transactions. So your transactions can be tracked back to you.Monero gained popularity because transactions could not be tracked back.
Now with the arrival of BitcoinConfidential which happens to be a sister coin of smartcash https://smartcash.cc/
