Beats me what is happening under the hood. I just installed Wallet of Satoshi and hit its Buy Bitcoin function which took me to Moonpay. Just getting started with doing zap through LN, so I'm just learning.

Don’t get me wrong, I’m totally new to Lightning. I used to mine Bitcoin with my GPU when wiping a drive and forgetting a wallet there meant you lost a few cents ;) But then dropped interest till not long ago.
Bitcoin transactions do have a price, but 16% percent I kind of believe it to be quite high
What I gathered when you use a Lightning wallet is that you first have to fund it with Bitcoin, coming from a proper Bitcoin transaction, its fees and settling time. Once the transfer is done, you have a certain amount of sats to spend on the Lightning network. I setup for fun and to learn this better couple of nodes in the past couple days. One is personal, one made to be public for anyone to have a wallet. Kinda Believe in this
