I also hope to get rewards like you, that's a very high income. I also hope to participate in the translation campaign, because it is very promising indeed.
You're right, translation is the best choice right now to get a lot of rewards in a bounty campaign. In my last campaign that i participated in, a translator participant even got rewards almost 32 eth. Very promising. I hope i can't participate in translation too, but unfortunately i can't because i don't have talent in that field.
But not everyone can do the translation. You need to have good English, and you've done many different translations before.
Reward for translation is very high. I have some friends doing translation. They earn at least 5000$ for each of their translations and sometimes 10,000$. That is a huge amount, if you only participate in media campaigns. At least you have to do 30 campaigns to get that amount
