Looks like they could be a decoded bitcoin transaction reference... You could try and copy/paste th "78ef....." bit into a blockexplorer and see if it displays a transaction. It certainly doesn't look like a private key... and the "tx" part would indicate that it was a transaction.

"Insight" is a Bitcoin blockchain API (https://insight.is/) usually used for blockexplorers like this: https://insight.bitpay.com/

Did you ever try and install it from here (https://github.com/bitpay/insight)? Or possibly you've simply verified a transaction and then saved it?

That's just a cache of a transaction which has no (recovery-related) information.
Just the raw tx or hex format of it depending on the client.

Like for example based on your given example (insight_bitcoin_tx_78ef....):
insight_bitcoin_tx_f782432c15e7656dd8c5b3f3832273f2a116ef374222373f6bbb59a63753d3d6.json

The underlined part is the transaction id of the particular cache.

Hello Friend

Thanks for your reply of my question about the " insight_bitcoin.." file.

also it is a BTC transaction or not? i mean i can recover my BTC or not ?

Thanks for your time

[nc50lc]

also it is a BTC transaction or not?

Yes it is, "insight_bitcoin_tx_78ef...." is for bitcoin transactions.
Copy the characters between "tx_" and ".json" (just like the underlined part above) and paste in on any blockexplorers to view that particular tx's information like inputs, outputs and the amount of Bitcoins transacted.

i mean i can recover my BTC or not ?

No, using that cache, you can't.

Since you're using Electrum on Windows, try to look for the wallet files inside the electrum data folder:
C:\Users\(Your Username)\AppData\Roaming\Electrum\wallets [Hidden by default]

But I highly doubt it since yours is more likely connected to a hardware wallet (trezor).
I can't help you any further.

Thanks for your reply of my question about the " insight_bitcoin.." file.
also it is a BTC transaction or not?

This file seems to contain transaction information. But it is not a 'transaction you can redeem'.
To gain access to the BTC, you need access to the private keys associated to the address.

i mean i can recover my BTC or not ?

You might start off with explaining what happened.

Which OS are you using ?
Which wallet are/were you using ?
How did you lose access to your coins / What happened ?
Do you have any backup (e.g. 12 word mnemonic phrase, xprv.. , QR codes..  ) ?

Thanks again for yours replies

[cyberclub]

With only this information, you can't.

Since you have found the file in the electrum directory, you most probably have used electrum ?
Do you remember installing it ?

Also.. did you do what nc50lc suggested ?

• Since you're using Electrum on Windows, try to look for the wallet files inside the electrum data folder:
  C:\Users\(Your Username)\AppData\Roaming\Electrum\wallets [Hidden by default]
  

This is the directory of electrum's wallet files (which contain all of your private keys).

how insight_bitcoin files can be on my PC ? is a proof a last missed transaction?

You can not 'miss' a transaction.
Transactions are broadcasted into the network. Once they are included in a block, they are confirmed.

You don't need this information to access your btc. You only need the corresponding private keys.

I doubt that transaction was even the OPs to begin with...

It looks more like a part of the "test" suite in the Trezorlib package: https://github.com/trezor/python-trezor/tree/master/trezorlib/tests/txcache

Given that it was under the Electrum install directory, possibly part of the tests related to Trezor implementation for an older version of Electrum.

In any case, even of it was some leftover transaction that did belong to the OP, there is zero chance that the OP will be able to recover anything without the appropriate private keys(s)
