Im kinda skeptical, how can we be sure that you will be paying us for the efforts? Do you mind putting some coins in escrow so we can feel more safe about the payment? Also, is there any maximum amount a user can get here?
I would be happy to put coins with a trusted escrow user, such as Dabs, as written above.
The article in the English Wikipedia about Bitcoin is around 7,500 words. So, assuming you translated every single word there, you'd receive P15000. I highly doubt someone will write that much in the allotted time, but I
would pay out in that eventuality. The same goes for the Ethereum article.
However, I would of course make sure that you followed Wikipedia's rules about citation, relevancy, neutral point of view etc before paying out. The reason is because I want the article to be long lasting and not deleted by Wikipedia's admins, that doesn't do any of us any good.
I think the best bet is to translate from the English article, as much as you want. That article closely follows Wikipedia's rules so if you translate from it instead of attempting to write original content I'll have no reason not to pay out.
