the more people start to use crypto as currency the more people will be interested for their privacy of transactions
privacy coins are the future!!!
You may be right, but the more people are using privacy coins, the more they come into the focus of politics. And from there is a short way to go before politicians label the use of privacy coins as a crime. Anyone who then uses privacy coins is a potential criminal. In some western countries this may still be okay because the consequences are tolerable, but in many others you will have to reckon with disadvantages and prosecutions.
