However, due to my intent to expose the blockchain data from this transaction, I decided to use an address from ChipMixer. The address was obtained using ChipMixer voucher codes that I set aside for this potential purpose in November. I always keep a moderate amount of money in Chip vouchers, just in case I need to do something bad for my privacy. The money for these vouchers may have been deposited by me anytime in about the past three or four years; thus, any blockchain observer who identifies Chip inputs will not find it feasible to guess which were mine.
There are multiple ways to use ChipMixer - it is great to see a person who understands their risks and plans how to achieve most privacy with the tool.
