may I ask I am new to this and I've been running my wallet bitcoin wallet since Saturday and still have 22 weeks how long does it take , and will it have to synch again once its done. sorry for high jacking the thread, but im just learning and reading thanks.
It needs to "keep up" with the current state of the block chain, so it is constantly downloading new blocks and receives new transactions. If you keep your machine offline for quite some time, you may need to sync for a couple of minutes or so. Yeah, look for downloads of the current state of the blockchain, that is faster!
