"There will be no problems with the exchange of our stable tokens"
Alone this sentence above shows that this project is not legitim; just avoid these kind of scams; I already worked with some legit blockchain projects and all were paying with bitcoin + ethereum and if you show better performance they gift you extra with their tokens.
If you call someone a scammer and do not show any evidence of fraud, it means that you are a liar and a slanderer.
That's just a user's opinion on these types of deals, and you can't blame them for speculating such things towards your project.
As you can see, most of the people's sentiments here about you guys paying in your tokens in exchange for translation services isn't well received and never will be.
Only those are very desperate and looking to have an additional list of project on their portfolio would accept what you're offering; and with that, you'll only get low-quality translations (most probably google translated ones).
If you're serious about making your project succeed, I suggest you guys re-evaluate your approach and start thinking about paying either in
BTCitcoin or Ethereum for the services you're looking for.
