My favorite are XZC because zcoin utilizes the zerocoin protocol to provide anonymous transactions in a unique scalable way. its a cheap privacy coin and i always liked it and have high hopes for it in the future
my second fav coin is NEO because i like the concept they are doing and i like the fundamentals, its a new coin that already made wonderful progress!
these are the only 2 coins im holding at the moment as well
what about you?

To play favorites is a bad idea. I advise you to estimate blockchains according to their technical characteristics and opportunities to earn. This will bring you more profit and patience.
