edit : how can i sync my wallet fast ...please need help.
Full wallet sync is way too slow.
Can I download byteball.sqlite somewhere by http or as torrent?
is it possible to use it this file taken from another wallet?
Syncing depends on your bandwidth and on the load of the hub you are using, you may have to try a hub other than the default one to see if it speeds up things. There's ByteFan's hub, (check out
https://byteball.fr for the nearest location). Having said that, syncing still remains slow, so maybe use the light wallet instead.
