Anonymity is not good for our future. I think the main purpose of creating crypto currencies is to bring the transparency and giving the control of the funds to the user who owns it which is not possible in case of banks and other investments unless you keep fiat stashed in your house in which case value depreciates because of inflation.

People associate anonymity with their right of keeping their money/property safe from everyone and want to use it as a tool to avoid taxes too but if you expect good facilities and security from your government for yourself and for family, then why should not pay the fair taxes on time?

If anonymity is added to the bitcoin, then anyone can fund the terrorist/illegal activities without anyone knowing about it which may increase the crime rate/illegal activities. People will try to convert their properties/savings into btc so that they don't ave to pay taxes and capital gains. Governments will lose a substantial part of their funding and in reciprocation, many countries will ban the btc and its trading in the country and any even criminalize it to hold and trade bitcoins/crypto currencies.

So in my opinion, anonymity won't do any good for bitcoin and for traders/investors worldwide. This is my take on anonymity.
