The conditions you want to dial are pretty heavy. If you pay BTC, you will have more demand. Is there any guarantee that the ChronoBank will be exactly 1 Btc in the end?
These conditions are mostly standard for any serious project to run a campaign this year. In fact, requiring only 50 posts in 2 months is about the lowest requirement of any recent project I remember. It averages out to below 1 post a day. Not much reason to spam when you just need to make 0.81 posts per day right?
As to guarantee of value? Given the initial valuation of TIME, this is a substantial reward for the time investment required.
Difficulty is translated, not for messages
The requested translations will normally exceed $ 2,000. You want more than one thing and the word is too much.
These are personal ideas. It's okay if you find people to translate.
