It's surprising how many people in crypto don't know what Lightning swaps are.
If you search for it, you'll get TONS of FUD results though. Lightning is kind of technical (like the rest of the crypto world), so I guess we need so see lightning in real use cases, before people actually start to care that much about it, it's a shame though, since Lightning is such a powerful invention, which will change the way we transact with cryptocurrencies moving forward.
Right now, the only people adopting Lightning are in it for the tech. Everyone who's in crypto for the money - i.e. the vast majority - don't see the incentive just yet.
The projects that do decide to build on Lightning to make it more accessible and profitable... The crypto world is their oyster. No one sees it coming just yet.
Lightning will probably blossom into something quite nice in the near future and it may just take a lot of people by surprise.
