BTC's USD value drops and increases if you haven't noticed and that's what we use to calculate your rewards.
At the time of calculation for WEEK 8, $1.70 is equivalent to 0.000066 BTC.
while on WEEK 7, it's 0.000072. hence the difference in total value in both weeks.
Next time, ask directly on pm rather than pointing this out in the open and speculating.
Well to me i don't see any reason of lamenting over $6 difference while the team spare out $30 for each qualified best poster for the week. Don't him know for this singular challenge the team may decides to remove the free bonuses if he wants to go in details of get his $6 difference.
From all your explanation you are absolutely correct @julerz12, because the bitcoin market is not stable like usdt were you could just calculated and delivers to the team and they pays exact value.
I think if he is not comfortable with the payment he can leave the campaign while others who wanting to join to occupy his slot.
We do not check the spreadsheet amounts, we trust julerz12 and simply pay out the amount specified there.
Why we have a campaign manager?
Sir he did the right job and has no mistake, it was only the price change after calculation I guess he didn't visits the market to know if the bitcoin price has dropped or changes. I Trust Julerz12.
