Hi one question. I have buy some Miner of Paycoin @ https://cloud.zenminer.com. Is this the right thread?

Because they dont mine anything

my (sha256)paycoin wallet won't sync. it's rubbish.

dont get it xD How i can buy a coin and how can there be profit?

They'll probably get it if they can demonstrate that PayCoin is an established cryptocurrency and people are actively using it and referring to it by that name. Prior use means nothing if the name wasn't registered. (That said, I am not a trademark lawyer..)

The registration process. Some people believe that registration is the process of turning a name into a trademark. Actually, it's the opposite. You can't get a registration unless the name already is a trademark. Once your examiner is satisfied that you have a trademark, registration is granted and that enhances your already-existing trademark rights. Registration gives the owner a presumption of ownership, provides constructive notice to other companies in the U.S., and offers the hope of incontestability (after a few years). Registration may also increase your payment in case of a willful infringement.

The unregistered trademark. As noted, an unregistered first user of a trademark can often claim trademark rights within the geographic selling area. But keep in mind that having an unregistered name is not the same as having an unregistered trademark. You can't claim trademark rights, unless the moniker meets the legal requirements of a trademark --  that is it's distinctive and associated with your goods and services.

that'll be difficult since the wallet don't sync
