I would like to know the best way to mix bitcoins. So far, I have read about converting to monero and then back to btc, I have read about using exodus wallet and then also seen the service of blender.io. I am not sure which service to use as it has been a very long time now since I have used a tumbling service, I would like to know which would be best to use.
I dont know but this one sounds an advertisement about blender.io. 
When it comes to mixing service then ill handsdown with Chipmixer for this time.Wayback there are several no. of these tumblers but already closed its doors
that why i highly recommend Chipmixer when we do talk about mixing.
