Jsstrippler(profit clicking) how to repay loan(free 10$)

Tweet

I had joined this program when it was jsstripler,used my free money and finally understood it was a loan after getting negative balance.now I started again in a the new profitclicking a week before. Now I used my free 10$ balance and earning 0.20$/day. Can somebody please tell me how to repay the loan, when to ,and how much money should i repay? All i know is i should buy one more position worth 10$ before 45 days. that repays my loan and am not sure about it. I dont want again to get negative balance. So someone please make it clear.
