another question..
It's good to update blockchain by the file: bootstrap.dat?
Then I can auto-update anytime normally??
I have find a torrent With a bootstrap dimension of 13.2 GB::
If you haven't started downloading the block data or started it for just a while, you could download the bootstrap using a torrent to save some time.
If you are already halfway through or the initial sync is almost completed, you can just forget about the bootstrap torrent.
