Just interested to hear people's reasoning for wanting NON-KYC bitcoin. Im guessing its so that one can deny ownership from "the man"
Bitcoin is already a "non-kyc" coin. We don't need to make any KYC or send any documents to be able to hold bitcoins.
Exchanges may (or not) require your documents because regulations demand them to do so. This is specially true when we are talking about tax gains, just like @LFC_Bitcoin said. THis is why regulations are so strict on exchanges, because governments wants taxes over your gains.
Although it is possible to avoid some taxes, it is very unlikely that we will be able to avoid all tax gains....
In my country we are able to sell about 6k USD per month without paying any taxes. This is a low value, but it is a way to avoid some taxes, even when you do KYC...
