Theoretically, you can get a transaction ID, a password hacker program, a new wallet and ......., Got banned from WGR Discord just for mentioning this.
Ziliqa (ZIL) and Nebulas (NAS) seem to be getting a lot of attention.
Not sure about NAS but ZIL does seem an interesting product that has got on top of the scalability issue so could become one of the big boys. Personally I think it has already pumped but others see potential for much more upside.
