Are you still noticing a lot of failures? I'll look into it to see if something changed with our node that's causing issues but I see a lot of successful payments going out too so it's not totally broken at least

Hi can you please email support@coinos.io with any details you have about this and I'll look into it

OP I sent you an email, can you reply to confirm that you have access to the email in your profile or give me another one to send to?

Please hold off for a week or two. The non-custodial wallets aren't working very well at the moment but I've got some fixes lined up.

No we'll still offer custodial accounts and regular old layer 1 non-custodial bitcoin wallets. Ark will be an optional separate account type for people to try and just another layer that we support receiving into the custodial wallet.

Eventually I might start limiting the custodial accounts so people won't be able to hold large balances there but will still be able to use them for small zaps etc.

Yeah this is a basic onchain-only BIP84 wallet. I quietly launched it over a year and a half ago: https://github.com/coinos/coinos-ui/commit/b008ad7a87ae101d814d774533ed36243b9b8457

I haven't been advertising because it doesn't work that well at the moment. We don't do a good job of keeping the balance and history up to date properly.

We're using Bitcoin Core to track all the wallets as watch-only descriptor wallets to lookup the utxos but I've found it's not really that well suited to the task of watching hundreds or thousands of these wallets.

I'm planning to host my own electrum server and use that for wallet balance lookups instead but haven't rolled that out quite yet. Should be coming soon though, maybe in the next week or so.

I would recommend holding off on trying these non-custodial wallets until then.

No but planning to support Ark soon

Oops guess I jinxed it

Ok Darth

shrug i thought it was interesting

no he's not, I'm the real adam soltys

I picked 5 because that's a round number that nocoiners are more used to evaluating mututal funds etc., not to cherry pick.

4 years is actually a stronger claim than 5:

1,050 out of 1,050 periods profitable (100%)

Not a single 4-year holding period in Bitcoin's history has lost money. The key comparison:
┌────────────────┬──────────────────┬─────────────────┐
│ │ 4-year hold │ 5-year hold │
├────────────────┼──────────────────┼─────────────────┤
│ Profitable │ 100% (1050/1050) │ 99.9% (958/959) │
├────────────────┼──────────────────┼─────────────────┤
│ Median return │ 1,382% (14.8x) │ 3,108% (32x) │
├────────────────┼──────────────────┼─────────────────┤
│ Average return │ 15,553% (156x) │ 18,229% (183x) │
├────────────────┼──────────────────┼─────────────────┤
│ Worst period │ +31% │ -12% │
└────────────────┴──────────────────┴─────────────────┘
The 5-year number actually has one losing period (bought Dec 2017 peak, sold Dec 2022 FTX crash bottom), but 4 years avoids that because 4 years from the 2017 peak lands you in late 2021 —
right in the bull market.

The worst 4-year return was buying in April 2021 at ~$58k and selling April 2025 at ~$76k — still a 31% gain.

So you could actually make a stronger statement: every person who has ever bought Bitcoin and held for 4 years has made money, with a median return of about 14x.

Yeah but I think they were linked to my twitter accounts which I deleted

Cool, done!

I think Nostr auth is already linked

Excellent report!
