there are now hundreds of nodes on the main net. there are multiple vendors (like bitrefill, torguard, the blockstream store) who are accepting lightning payments. so it’s definitely coming along.

but in general, it’s still in a testing phase. developers are suggesting caution and that people only commit small amounts to channels as wallet devs build for edge cases. even devs are still losing money in channels right now, so i wouldn’t commit anything you’re not ready to lose. hopefully in a few months, it’ll be ready for regular end users.

given how excited bitcoin and lightning developers are, and how much time they’re putting in, i’m sure it will be successful. it’s just a matter of time.
