What is lightning?

Instant & cheap bitcoin transactions.

How can I try lightning?

An easy way to try the lightning network. Just visit tippin.me and sign up. Use a bitcoin lightning wallet such as lightning-wallet on android. On iOS there is thin wallet but that is not yet opensource. Follow the instructions in the app you download to create a payment channel and send some satoshis to your tippin.me account.

Why is it useful?

You can pay by lightning on a growing number of websites.

You could try reading a post on yalls.org or buy a phone voucher on bitrefill. You could also try sending me some satoshis by visiting my tippin page, tippin.me/@6102bitcoin.
