I'm thinking about Byteball (still unpopular, but I like features that they offer) and BTC.
Last but not least is Dash, it seems to be a rising star, b.c. I see that increasing number of exchanges and crypto-ATMs support it
There are several coins out there and if you should go by the advise of people, you might be misled by some scammers, I would like to tell you, make research about some different coins, probably on the top 100 cmc.
