Most of the coins have already been pumped. I am convinced that privacy coins will be major in 2018. One of the best (if not the best) privacycoins is XSPEC. I consider it pretty much the best privacy coin, the tech is impeccable, it has TOR with OSBF4 integrated, it is very fast and low power consuming and backed by a very strong team and community. Still very cheap for its value, 2018 will be a good year for Xspec. Buy some, you will thank me later .
