I saw this 'challenge' from @dragosroua recently. I'm definitely into more than 5 crypto assets but here are five that I'm investing in. All in small amounts.
Steem
There is no doubt Steem exceeds all of my other crypto investments simply because Steem can be earned on this platform. I don't think i need to shill any further.BAT
Basic Attention Token aims to change the way display advertising works, i.e. advertisers pay for your attention and if i'm not wrong you can earn some BAT for giving your attention.Enjin Coin
Gaming is a big industry and a crypto that would allow you to trade in-game items for real money is a winner.Ark
Ark only has a wallet at the moment and hopefully we'll see the Smart Bridge technology actually work. Based on their road map, most features are still in progress.IOTA
The only one based on Tangle rather than blockchain but is quite similar. Main points would be scalability and transaction speed (and their partnerships with companies).
