take alot of time? its mean i need alot of bandwidth data?
i've tried to install ethereum wallet from https://www.ethereum.org/
it took more than 7days to download all block and wasting alot of my bandwidth everytime i need to open my wallet
and finally i just use myethereumwallet.
so do i have to go just like that?
If you are going to download a full node, then yes. The current size of the blockchain is about 150+ GB. And the verification takes quite some time.
But you could also instead just download a light weight client (without the whole blockchain). Those clients check the balance of your addresses via online services.
Like other already mentioned Electrum (https://electrum.org/#download) would be a good open-source light weight wallet. Download, install, start. No much hassle.
150+ GB?? well, thats alot of volume.
you mean a light weight electrum client wallet??
