I'm running a self-hosted Umbrel node on a Raspberry Pi that handles both Bitcoin and Lightning Network nodes. The built-in app store is pretty fun to explore too. 

Recently I came across the ipollo G1 mini online and am thinking of buying one to try Grin mining (though I'm not sure about its daily output – ​​what's everyone's take on Grin?​​). 

Also, does anyone have recommendations for other interesting crypto gadgets?

What fun crypto hardware devices is everyone using?

In the future, when humans colonize the Moon and Mars, which currency system do you think the entire human civilization will use for value exchange on Earth, the Moon, and Mars? Please provide two currency systems, one is your own creation and the other is an improvement on the existing value exchange system. In addition, how likely do you think Bitcoin and Lightning Network architecture, combined with other existing human technological achievements, are to achieve this goal?

In the future, which currency system will humans use on Earth, Moon, and Mars?

How many Bitcoins do you think were permanently lost in the California fires?

What is Umbrel? Check this out: https://umbrel.com
I use Umbrel for several years. It's not perfect, but I still love it. Here is what I do with Umbrel.
1: I use Bitcoin Node and Lightning Node to run bitcoin and lightning services.
2: I use Tailscale to access my Umbrel with my other devices.
3: I use File Browser to upload movies and tvshows.
4: I use Plex to start a meida server, and stream on my Mac and Apple TV with Infuse.
5: I use Nostr Relay to backup my nostr information.

What cool things have you done with Umbrel? Welcome to share!

@LNRocks's bio

(Rant) The bitcoin subreddit is basically a degenerate gambling forum

satgoob

Because for most people, bitcoin is gambling. They know nothing about bitcoin and they don't care. They buy bitcoin just want to be rich overnight, nothing else.

What kind of new hardware devices will emerge for Bitcoin in the next 5 years?

A non custodial wallet with full bitcoin node(699GB now) on a phone.

The Bitcoin Ecosystem Map is so good.
Blixt and Zeus are light end wallets. I mean we can have a bitcoin full node & lightning wallet on a phone. Need a phone with 2T storage maybe.

Now we have hardware wallets(Ledger, Trezor, Jade, etc) and bitcoin nodes(Start9, Umbrel, etc).
Maybe we can run lightning node on phones one day.
Are there any other interesting hardware devices out there nowadays?
And what kind of new hardware devices will emerge for bitcoin or lightning in the next five years?

What assets do you think can increase 10x or even 100x in the next decade?

I don't know， so come here for potential answers.

What assets do you think can increase tenfold or even hundredfold in the next decade?

Is there a device to backup recovery phrase that can be carried with one?

Store the recovery phrase Physically, not digitally.

Steel board and steel capsule are too big to carry daily. Is there a device to backup recovery phrase that can be carried with one? Something like a key pendant. Not ledger or Trezor wallet. Just a device to backup the recovery phrase.

Is communication protocal built on Lightning possible?

Can you write more, please. Why no one should do it?

Now, sphinx chat is built on Lightning. But it's not a protocol like Nostr, it's an app. 
Will an open protocol that is used for communication be built on Lightning possible? Third party applications can use this protocol to chat, stream, etc. And is it necessary to build a protocal like this?

What's your favorite service built on ⚡ lightning?

Umbrel node. Nostr, Sphinx chat（Hope communications on Lightning can be used more widely）

Bitcoin products we need

1. Prove itself is the better way of storing value for more people.
2. Information(messages，vpn, etc) routing on top of Lightning. And more merchant support for Lightning payments.
3. The ability to penitrate network blockade is very important for Nostr. 

nostr

Sphinx chat is based on lightning network. Messages routed together with the lightning payment.
Nostr protocol is based on relays and clients.

How do you compare sphinx chat and the nostr protocol?

The ability to penitrate network blockade is very important for Nostr. Otherwise, it can only be a transition protocol. Hope you can write up an explanation to inspire more people do the work.
