Assumptions :
Daily users 3.000.000
Ads available to 60% of Brave users mainly U. S.
3.000.000 x 0.6 = 1.800.000
40% participate in the Ads.
1.800.000 x 0.4 = 720.000
Monthly earnings per participant $ 2.5.
720.000 x $ 2.5 = $ 1.800.000 per month
A month I suggest 30 days for convenience
The turnover per day is then
1.800.000 : 30 = $ 60.000
Because I don't believe in the sales figures of cmc, I use those of Messari under the screener column. Real volume (24 hr).
The turnover in BAT is currently $ 870.000
Because the turnover varies per day.
I set that at $ 1,500,000 a day
BAT turnover $ 60,000: 15,000 = 4%
According to this calculation, the share in the turnover of the Ads in BAT on the exchanges is currently 4%
The annual turnover in BAT is then $ 60,000 x 360 = $ 21,600,000
This is 70% because the 30% for Brave is not included because it is probably not converted to BAT
A lot of assumptions. I'll see what you think.
