Questions about bitcoin qt

[kira4light]

The bitcoin qt really takes a lot of memories every time when it's running. It normally takes like 3 minutes to open up!

Is there any suggestion on lighter, easier-to-use wallet?

People are saying that on-line wallet is not safe. Any suggestion on that?

If you want online secure wallet Blockchain.info
If you want a software client (like bitcoin-qt) use Electrum (http://electrum.org/).

hello

i installed bitcoin-qt (0.8.2) for mac osx (mba), and whenever i run it, it takes up all the cpu. is this normal or happening to anyone else? maybe i am missing a setting somewhere?  as a side note, i found a nice free command line tool to throttle processes http://www.willnolan.com/cputhrottle/cputhrottle.html that seems to work well.

cheers.

It takes 3 minutes because it check the last blocks before starting 

Use Multibit or Electrum, no need to have the whole blockchain.

Pure online wallet of course aren't safe, the owner can steal your bitcoin. But a online wallet like blockchain.info one is safe because they don't have access to your keys. Just make sure you make backups!

and whenever i run it, it takes up all the cpu. is this normal or happening to anyone else?

It is verifying the blocks it download, of course it use the cpu. Is it a problem that your computer is actually used? Because that is why computers exist: to be used.

If you use an android device, consider Bitcoin Spinner (or the latest, beta version called "Mycelium").
Again, private keys are only kept on your device. Just make sure you back them up.
Bitcoin-qt client is fine if your computer stays on most of the time.

So it is normal. Thanks for the information. The problem is that I want to use my computer to do other things in the meantime, which at times can be affected by overall CPU usage of course.

Anyway, I tried Multibit and like its convenience. Will check out Electrum. Thanks.
