I met someone at the Lightning meetup last night who had lost a decent amount of sats when BlueWallet shut down its custodial node last year. They gave users about 2 months to withdraw after posting a message on their blog. There were no notifications or updates to the app to inform users who didn’t know this was happening. I warned people here, and hopefully helped a few people. But I’m sure there are some who simply gave up on Lightning after this. For some, it might have even been the only time they ever used bitcoin. It’s frustrating because it’s too late to do anything about it now.
