I lost my BTC.

[A.Delaney]

So back in early 2018 I was mining on Kano and had my rewards sent to an address that from what I remember should have been my trezor. I haven't had any other wallets. I had over 100 payouts totaling just over .4 BTC. I stopped mining in mid 2018. Fast forward to today. I plug in my trezor on a new computer, download the software, updated the firmware and my balance is no where near .4 BTC.  None of those transactions are in my history. Only a few smaller transactions I made several years ago are there. I thought well maybe I was wrong about what I mined. Nope, I checked Kano for my reward history and it is just over .4 BTC like I remembered.  Where did it go? The thing that gets me is there is no way I would have mined all that without checking my wallet to see the balance. Especially the first payout because I would have wanted to see it show up. Since I updated the firmware it gave me a new address. Is there any way I can determine if the address I have on Kano is my old trezor address? I don't know what else I can do.

Did you make those smaller transactions to the same address or to a new address? And didn't you check your Trezor after those transactions?

I checked Kano for my reward history and it is just over .4 BTC like I remembered.  Where did it go?

I assume Kano shows which address it went to. You can check it in a block explorer.

The thing that gets me is there is no way I would have mined all that without checking my wallet to see the balance.

So it should still be there. Do you have the seed words for your Trezor?

Since I updated the firmware it gave me a new address.

That's normal: you should use a new address for privacy. But the old addresses should still be there.

Is there any way I can determine if the address I have on Kano is my old trezor address? I don't know what else I can do.

Maybe it's a caching problem. I've seen this on Ledger several times. Does your Trezor app give any option to wipe it's cache or something to force a recheck?

[A.Delaney]

Yes all the transactions were made to the same address.

Yes Kano shows the address all the payments were sent to. I’ll try a block explorer for that address.

Yes I have the seed words for my Trezor.

I’ll have to check on the cache and report back.

Yes all the transactions were made to the same address.

In that case, if you have access to some of the later transactions, you should have access to all transactions. Worst case you can export the private keys from your Trezor (using third party software offline), but I assume the Trezor software can handle this too.

With over 100 inputs, you're going to want to read my topic on consolidating inputs so you don't waste too much money on fees once you can access your Bitcoin.

@A.Delaney, you are not the only one who encountered this problem, but the matter can be quite banal and easy to solve if you just need to enable the accounts you had before, but now they are not enabled after the firmware upgrade - go to settings -> crypto tab and look what is there.

If that doesn't help, maybe you used a passphrase (additional protection in the form of a password) that you need to enter to gain access to the account - the seed you have is correct, but it is possible that you can only see the account that is not protected by the passphrase.

I found it!!!  It was in a hidden wallet that was passphrase protected. I did not see that before. Thank You both so much!

Always good to see coins get found.

Most of the time this section talks about lost coins and I would venture to say many times they are not recovered.

For the record, that means it wasn't sent to the same address.

It's a bit misleading to call it a passphrase if the Trezor wallet told you to enter some text that will be combined with your seed phrase, since this combination will literally derive different addresses, private keys, master private keys, and so on. It can be a bit tricky to remember, which is why you *always* have to write down the seed passphrase if you are using that particular feature.

This is certainly good news and perhaps another opportunity to warn all those who will someday find this topic to understand how important it is to keep such sensitive data safe. Over the years, here on the forum, there have certainly been dozens of cases where people claimed that they had the correct seed, but that their balance was still 0 when they did a wallet recovery - and in a good part of the cases it was precisely the fact that they had forgotten that they had an account that was protected by passphrase.
