I suggest that large amounts of coins must be mixed slowly, ranging from 10 to 100 BTC every day. Hackers are unprofessional about Bitcoin mixing, and the details are not done well. Hackers think that mixing through chipmixer.com will be anonymous, and the blockchain is public. The data exists forever and anyone can access it at any time. "Total anonymity" is a university question. You can’t make mistakes. Chipmixer.com can only cut off the tracking of input and output, and adds a lot of anonymous features. Chips, each chip has tens of thousands of times the address for you to hide, merge, split, spend at any time, or temporarily spend, and there are many more) This is great. If you use it correctly, the security agency cannot track the source. If you want to be "completely anonymous", follow-up work depends on you. The hacker’s mistakes are merged together. This is a fatal error. Even a lot of private key bitcoins are sent to the same address. This is a failure, so it is easy to trace. After all, few people mix more than one hundred in this time period. Bitcoin, it is easy to think of what hackers do. The correct approach is to send each private key to an address and must not be merged together. Only by doing the details can you successfully mix the currency.
