How many Bitcoins get tumbled each month?

[irukandji]

I saw a claim that a couple of years ago 250,000 BTC were tumbled each month. But that seemed a lot. Are there any figures available?

You can't really know these details unless mixers decide to disclose them clearly (and you need all of them to do so in order to get an accurate number). The Darknet is thriving, I wouldn't be surprised to know that bigger amounts are being tumbled.

it takes accurate records to know how many falls each year but I think it's impossible to ascertain by the count of bitcoin every day unless you search and calculate everything how many fall every month
