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.
If it is about fees problem on usage of wallets services, in my experience in blocktrail.com before becomes btc.com right now, they have big fees be compared with other wallets services, the fees about 0.001
BTCI have stoped using btc.com wallet, i use mycelium for bitcoins because the fees is low about 1-2k Satoshi and jaxx.io for altcoins (DASH,eth,etc, and other that be supported by jaxxio).
