My native language is Chinese, my English is not very good, there may be errors, please understand. I suggest that large amount of mixed currency must be slow, mixing 10-100btc every day. Hackers are not professional in comparison with special currency mixed currency, and the details are not well done. Hackers think that they have passed chipmixer.com If you mix, you will be anonymous. The blockchain is public, the data will exist forever, and anyone can access it at any time. "Complete anonymity" is a university question. You can't make mistakes, chipmixer.com It can only cut off the tracking of input and output, And add a lot of anonymous features (pre installed chips of different sizes a few weeks in advance, each chip has tens of thousands of addresses, so that you can hide, merge, split, spend at any time, or spend a few months, and many more) this is great. If you use it correctly, the security agencies can't track the source. If you want to be "completely anonymous", the follow-up work depends on you. The hacker's mistakes are merged together. This is a fatal error. It sends many bitcoins of private keys to the same address, which is a failure, so it is easy to trace. After all, few people mix more than 100 bitcoins in this period of time. It is easy to associate with what hackers have done. The correct way is to send each private key to one address, and it is absolutely not allowed to merge them together Only in this way can we successfully mix coins
