In reverse order of the posted video with my own commentary.
EOS - Taking Ethereum's place and Steem, and Bitshares.... while not application specific, if the performance targets are practical at scale EOS' future looks good.
Golem - Another distributed computing project. Huge potential, huge technical risk to overcome
IOTA - Is it a coin or is it a protocol? There are other DAG/Hypergraph blockchains available. Regardless, is there an incentive to use it other then no fees?
SALT - BOSS platform for the cryptowealthy. With the new tax regulations allowing for every crypto txn being taxed why get taxed when you convert to fiat?
OMiseGo - Ambitious -Backed by an All In Established Business and overall price history looks sane
