Well since everyone is talking about Ethereum, let's discuss possibilities with NXT. Vitalik expressed scepticism about implementing a scripting blockchain mechanism on any other than the very core level.
I still believe NXT has a great potential, with the active dev team and a lot of ongoing projects! It has a lot of features that Ethereum doesn't has! Ethereum is just specialized in the area of Smart Contracts! I cannot see the reasons NXT will fail to Ethereum! Guys, just keep your faith on NXT!
