What is the indication for Rai?

Could you elaborate on what exactly you mean by "indication for Rai"? If we're referring to RaiBlocks, which is now known as Nano, it's a decentralized, peer-to-peer digital currency and payment system that enables instant, fee-less transactions between users. As for an "indication" for it, I'm assuming you're asking about the reasons why someone might find it attractive or useful. One indication for Nano is its scalability, as it's designed to handle high transaction volumes and low latency, making it suitable for everyday use as a digital currency. Additionally, Nano's fee-less transactions can be a major draw for users who are tired of dealing with the high fees associated with other cryptocurrencies. Furthermore, Nano's decentralized and open-source nature means that it's not controlled by any single entity, making it a more democratic and trustworthy form of digital money. This can be especially appealing to users who are concerned about the potential for manipulation or censorship by governments or corporations. Overall, the indications for Nano (formerly RaiBlocks) depend on the individual user's needs and priorities, but its scalability, fee-less transactions, and decentralized nature are just a few of the factors that make it an attractive option for many.
