We all know latest problems of BTC and coins with anonymity options that went up big with marketcaps and prices per coin.
In top10 (BTC is being number one so excluded) we will find DASH XMR ZEC with prices of 90, 60 and 20 USD per coin.
Like BTC has loads of forks same this coins have forks or technologies similar to them. Some of such coins already pumped, some doesnt seem to have a chance. Yet here are few i find interesting.
4 Interesting Anonymous Cryptocurrencies
EXCL - 3 years old clone of DASH with PoS instead of PoW.
GBYTE - Orginally called Byteballs. Have option fo Blackbytes which is so anonymous none exchange for now can even trade it.
XZC - original Zerocoin technology implementation. Even before ZEC launched.
ZDASH - fork of ZEC but with Bitcoins coin numbers, block halving and such.
None of them is on Poloniex when writing this post which means they still have some profits to gain.
