How is this a scam? They are offering a certain number of coins for work to be done. The exchange rate of these coins is publicly available information.
Read the thread ,he plays with numbers making people think his tokens are worth something which they're not ...and never will be !
You know how this board works ,most don't read half of the posts .Of course ,there's gonna be naive people who will say yes ...only to realize once they've done the job (which isn't an easy one) that they got screwed .
That's kinda like all those airdrop forms who ask for private keys .No one is forcing you to give it but there is always gonna be people who will give it anyway.
So yes ,I call it a scam .
So because the people don't do their research and read the terms of the deal, it becomes the bounty provider's fault? I'm sorry, but as that may be greedy on the provider's part, it's just as greedy for the bounty hunter for not doing their due diligence and research before accepting the job. In this case, I don't see any fault with what the OP is doing, other than being greedy. It's definitely not a "scam" as you call it, though, unless as @MadZ stated, someone did the work and he did not pay what was agreed upon.
