Is this risk below related also to stealth vertcoin addresses?
"Secondly, the key feature of DRK, anonymity, is also its greatest weakness for going mainstream. You have seen how hostile governments have been to just Bitcoin, which transactions can be traced in. Now imagine DRK popping up into the mainstream, do you think governments will sit idle and let businesses accept it? Some might, others will clamp down even harder than they did with Bitcoin. Countries that are friendly to Bitcoin now might not be friendly to a coin that has money laundering built right into it. Yes, a government can't stop the protocol, but they can stop businesses from accepting it by making the use illegal. Most likely, this would not be hard to achieve as they could simply make the argument the main use of the coin is for money laundering. If they made it illegal, it won't stop it being used on the black markets, but it will stop it from ever going mainstream because everyday businesses simply aren't going to break the law to allow a new payment method. So its growth potential would probably be limited to the black market. I don't think you would ever see Amazon or any big company using it, because of the backlash and the government crackdowns.
This is something that a lot of people don't realize I think. They think "hahahah government can't stop me". No, they can't, but they can stop the coin from ever reaching a mainstream audience. Litecoin has a good rep. Its the oldest alt coin still around. Yes, the technology of DRK is far superior, but it won't really matter if the government(s) never allow it to be used to purchase everyday things. Bitcoin and Litecoin are just starting to be viewed favorably in some countries, things like DRK will not help cryptocurrency as a whole because then it gives government a reason to crackdown."
