few users above already answer on the part: "what is a bitcoin mixer", so I won't back on it, as their answer above was already useful, but, if you want to use a bitcoin mixer, choose is careful: most of them a scammy ... unfortunately.

just an advice: if you want to mix your coins, DONT use any clearnet mixers! never !

grams have made "Helix"  (their own mixing service ), and even if it's not the cheapest one in term of fees, it's probably one of the most reputable and honest ones.


Kind regards
