I just started out so I missed on some of them, but the current one I am holding for big returns is:
ChainLink - I believe it hits every single point on your criteria and I think in the short term it will hit $1 but the more crypto grows the more valuable LINK will become.
Monetha - Paypal for crypto. I think it also fits your criteria and though I am not a fervent believer in MTH I think it will do well.
WaltonChain - I am big on WTC. Even though it's bouncing around between $1.25-$1.80 do to the China bans, RFID + Blockchain is a killer combination. The business connections WTC has are second to none with ICON being the only other coin I have seen that can rival their connections. The biggest problem was the communication issue, being Chinese they were focusing on China first.
I plan on going crazy on ICON as soon as it is released on EtherDelta, I believe that one will be huge.
