TWO heavywights:
Neo is advanced Ethereum backed by chinese mass
IOTA the ultimate peer to peer transaction technology (TANGLE) regardless the price.

nimiq is like a tiny, swift, promosing technology for p2p transaction, mining can be done on browser by anyone as mentioned, come this december, they are lunching the mainnet that will tell where they fall, very very interesting.

the underdog, after buying, watching, using , is DNR ( miracle happens in cryptos, this will go 1000)
