Lightning is built on top of BTC but it IS NOT a bitcoin address.
My system converts Lightning BTC into Hive. It also allows Hive or HBD to be converted to Lightning and sent to any Lightning wallet.
If you want to play around with small amounts of Lightning I recommend the Wallet of Satoshi app, it's a very easy starting point.
Thanks, so it is like "exchange" service , directly accessible through Hive.
