Beware that ltcminer.com is a BIG SCAM they will lock in to the first version and when you want to upgrade to v1.4 they will just rip you off I have sent them serval emails even with the transaction ID numbers and the addresses that the coins went to avoid sending anything money or coins to them. I`m pretty sure I know what happened to the site, the owners of dont care because their over sea in London and there’s no regulation stopping them from SCAMMING you.
