I still can't understand how will it work and why should RDN token go up in price? Can smb explain me pls or share link on video or article to understand?
There's lot of information on their website
https://raiden.network/Generally, it's off-chain payments solution for Ethereum network - similar to Lightning Network for Bitcoin.
As with other crypto, the value comes from usage - if Raiden will be used widely, there will be more demand for its token, and the price should rise.
If the tech will not prove itself useful, then forget the price rise.
