I think privacy coins will be big in the next couple years. With the U.S. Government changing the tax laws and other countries around the world trying to crack down on crypto, a way to hide what you're doing with them will help tremendously.
Yes, I agree. Privacy coins like Verge (XVG) will be more important in the future, and not only for illegal use. Some of them have also a very fat transaction speed and low transaction fees. I really think that the best of them will have a much higher market cap then today in a few years.
