So one tweet once in a day which will be equal to 0.007/week right ? and also there is a limit of 10 tweets so it means that we will not be paid for 11th tweet ?
That's right. At the moment I put that limit cause I don't want you to spam your followers, and they'll probably have seen the message anyway after 10 times. So for now I put it at 10, you can choose yourself over how many days you divide that but it has to be at least 10 days (1 max per day).
When I do payments I will look first if your account has not over 50% bots and it has at least 100 followers. After that I will check how many tweets you made and sent 1mBTC for each tweet to your CoinRoulette account.
