Why woud you not be interested in a coin thats completely decentralised, instant and completely free with transactions costs?
Completely decentralized? Nope! RaiBlocks/Nano maintains everyone's balance in the cloud. When you transact, this action is bounced up to the cloud allowing the cloud to adjudicate double spends.
The bad part: AFAIK, there is no security on the balance list. A node that just came online can't be sure it received the correct state.
