According to that analyze (no one knows how fair it is but still...) only 10.8% of mixed funds are 100% linked to illicit activities (8.1% - stolen funds, 2.7% - darkn). If we consider that this numbers are true, then what do you think, would this number be lower or higher in 2016? I guess higher... Do you agree with me?
But still roughly take 10%, in 2016 bitmixer mixed 1 Million bitcoin, 10% of 1 Million is 100 000. How much bitcoin was in circulation in 2016? 16 million but at the same time 4 million is lost (according to 2017 statistics) so what numbers we got? 12 Million. 8.3% of overall bitcoins were mixed via bitmixer alone. At the same time there were very popular mixers like cryptomixer, bitblender. So a lot of bitcoins were mixed, right?
You started throwing numbers around you've lost count of what's more important comparing things that are related, not apple and oranges.
The average output value of all bitcoin transactions in a day is at around 200 million bitcoins.
So rather than 8.3% of the total supply is more like 1.5% of all transactions went to bitmixer.
That's what fun about statistics, you can take two accurate numbers that are both true but show a totally different picture.
