These things are not simple for us normies. Quit getting pissy. You had to be an unhelpful bitch 2x before you were willing to simply paste a link.
Not only is he being an omega asshole I don't even think he answers anything correctly, because he is assuming everyone wants to be sovereign citizens self hosting full nodes, or wont even be open to the conversation of an alternate more compatible solution.
He is a tragic personality trope. Literally a poster child of the "ackchyually" meme.
In order to continue USING blue wallet, you have to run lndhub which requires running a full bitcoin node with lnd, open channels, and self managed hot wallet to fund it.
If he was a human who wasn't completely bankrupt of empathy and trying to make Bitcoin and Stacker News his entire identity like some dipshit way too into sports or politics he may be capable of providing an accurate answer.
But alas, here we are.
So, to continue using Blue you will have to go down the path of self custody or connecting to a lndhub provider.
Otherwise, you will want to look into other wallets such as Muun or Wallet of Satoshi. Phoenix is also an option.
I would probably suggest Muun. Its as easy to use as Blue if you're not looking to dive deep into running your own node but honestly they are all great wallets and I suggest maybe just throwing a tiny amount of sats in each and giving them a spin to see which ones fit your personal nuances a little more.
I personally went down the path of setting up my lightning node. It is really fun to learn! One of the biggest problems I ran into though is most nodes you try to open channels with want you to have 0.005 BTC in the channel minimum, which is not what I am looking to do if I want to open a channel and buy a $20 dollar gift card.
I would like to be able to open much smaller channels. Which brings me to my final point. Not everyone even has the financial means to keep channels funded or even meet minimum funding requirements when they had just been using Blue to interact with the lightning network in small amounts in the first place.
Darth is tone deaf as fuck.
