The blocks they mine show up on the blockchain is what makes their farm legit.
It seems you're rather uninformed on the subject. Which makes it really regrettable you chose to invest money with a service you don't understand.

While any site at any time may take the money and run, there are several simple tests that prove they provide at least the service they claim to.
CEX provides full transparency on the blocks they mined and how much you got paid from each block.
All of that can be verified on the blockchain.

And that's exactly what pbmining is refusing to do. Provide simple verifiable proof they actually mine bitcoin.
And that's why pbmining is widely considered a scam.


Now, before people invest with CEX or bring up the high price per GHS.
It's a very different service and you should expect to make profit out of trading GHS, not primarily through the mining rewards.
The mining rewards are easier to be seen as being paid interest on holding GHS.

But their transparency is an example of how a mining service should be run.


We're not asking for pbmining to disclose where they live and sleep. Although a business address is very much preferred over than anonymity, there is the slightest chance their concerns regarding their safety is valid.
All we're asking for is simple transparency in their mining operation by disclosing information which is entirely unrelated to their identity and in no way would reveal their identity.
Failing to provide this trivial and non-identifying information is the biggest red flag in their entire operation. And that's why a good number of forum posters have repeatedly warned people to not use this service.
