Also, if you do not want to download anything use an online wallet like blockchain. I think it is more convenient to use an online wallet and it much less hassle free and for beginners. But downloading and understanding the core wallet ultimately makes your bitcoins much safer. That way the bitcoins can even be carried with you on your usb if you would like to.
can any one tell me how to use bitcoin core qt without download the whole 40gbblol
that will end my internet storge:)
block chain take many fees i will try for coinbase

i think you are mistaken, blockchain.info does not charge a fee to use their wallet..
you can also try btc.com this is owned by bitmain, makers of antminers.
Coinbase covers the bitcoin fee. That makes it cheaper to use.
However, they control your money, not you.
