RISE is much cheaper than LSK, and it will implement more language, now supports C# SDK, just stay tuned. Maybe your LSK younger brother RISE will go to da moon earlier than LSK older brother.
Pardon me for my ignorance, but why do you call Rise as Lisk's younger brother? Is Rise built inside the Lisk platform?
Rise is just a fork of lisk that is a fork of crypti, at the moment none of the project is 'really' has built a working blockchain app.
what the hell is rise? another clone?
not even Crypti? Isn't the project like 2 years old?
With none of the projects I meant Lisk and Rise.
