BCH (bitcoin cash) recently had a mgnificent runup, as the BTC ("normal" bitcoin) had a steep drop.
ALT coins have taken a bit of a beating as well lately, which probably sets up some good buy levels.
Bitcoin Cash is basically a version of bitcoin that enables a larger and faster transaction speed.
We will have to see how this develops, but if BTC is not doing anything to improve on their slow transactions and other limitations, then it could very well be the case that BCH will in the future be the more preferred bitcoin to use as a means of payment in the realworld.
Some ALT Coins to look at here as well on the privacy side, that has lost some ground in the last few days are:
PIVX (first proof of stake coin with zerocoin protocol)
NAV (another privacy coin) and ofcourse
ZCOIN (only about 3 million supply according to https://coinmarketcap.com/currencies/zcoin/)
Below is the chart of BCH (buy the dip ?)
