Some examples...
Nothing appear in your explorer and while trying to move former BTC coins with https://github.com/Ayms/bitcoin-transactions people get "An error occured: 16: bad-txns-vin-empty. Code:-26" which basically means that the corresponding inputs do not exist
@Ayms how did you obtain your TX inputs? Note that BTCP is not a "real" fork of the bitcoin blockchain. You can locate your TX ID on the BTCP chain with their block explorer (https://explorer.btcprivate.org/), however you need to convert your addresses:
For P2PKH addresses, the corresponding BTCP address start with "b1" (Base58Check version 0x1325)
For P2SH addresses, the corresponding BTCP address start with "bx" (Base58Check version 0x13af)
@Ayms see also @ymgve's address converter script, https://github.com/ymgve/bitcoin_fork_claimer/blob/master/convert_address.py

Some that I know (not mine, especially the one with a big amount of BTCs)

No, BTCP is a real fork of BTC, then you should find your BTC coins there, but we don't currently

Yes, thanks, it's trivial, see also https://github.com/Ayms/bitcoin-wallets

It is not a real fork. It does not contain the BTC blocks from the genesis block up until the fork block.
Instead, the creators have manually funded all BTC addresses at the fork height. This means all TXIDs on the normal BTC blockchain are invalid in the BTCP blockchain, and you have to track down your TXIDs related to your address manually in their block explorer.

Let's not play with words, they have remined all the utxos in their blockchain, so of course you don't have the same blocks but same BTC tx ids should be there, and they are not

Do you mean that they did the same than "United Bitcoin and the God mode or The robbery of the century" https://gist.github.com/Ayms/86309b48084087a82634615d209f8b26
Certainly not, amateurism can't do this
@ymgve Do you have an example of BTC coins there?
@Ayms no, absolutely not. You won't find the same "BTC tx ids".
The "BTC tx id" is just the double-SHA256 hash of the serialized TX. Only the UTXOs at the time of the fork are re-mined in the BTCP blockchain in the form of coinbase transactions created out of thin air. These TX obviously will not retain the original TX id. Like I said, the only way to track them down is to look up in the block explorer (or if you have your own node, look up the address in your UTXO set)
Here's my address on the BTC blockchain:
https://blockchain.info/address/1HDW5sy8trGE8mEKUtNacLPGCx1WRtebnp
Here's my address on the BTCP blockchain:
https://explorer.btcprivate.org/address/b1Lghm4p8e1JLG3YtS2oZCqMwqDiahRhSkQ
Both of these addresses are the same, encoding the hash160 'b1df48437bc20058305dc266c4216afa5ba63fd1' (You can use http://lenschulwitz.com/base58 and see for yourself)
See how all the coins in the BTCP blockchain says "No Inputs (Newly Generated Coins)" instead of being the result of earlier transactions?
See how none of the BTCP TXIDs are present in the BTC blockchain?
That's what I mean by not a true fork.
I am using @ymgve script: convert_address.py sourcebtcaddress b19myfKHqRLAVKwu4BSysu3qjjtoPWtaRQo(arbitrary btcp address, always the same)
I dug out a couple of random examples and converted them as per the script above, looks like I am only able to get btcp addresses that contain transactions and coins when the source btc address starts with 1, but nothing for the ones starting with 3.

Am I doing something wrong?
@holuan You're doing it wrong because your addresses start with 3 (Base58Check version 0x05) and the corresponding BTCP addresses must start with "bx" (Base58Check version 0x13af)
You need to supply a P2SH address to convert_address.py, for example use bxk5hXBKgzqLr9Vm2zaZmHAmwUnwm5YRYUe.
Well... before posting this nothing appeared in BTCP explorer for BTC and now, all of sudden, even if I checked before posting (and still nothing), everything seems to be there (dated now 3rd of March)
And indeed it seems to come from nowhere (ie newly generated coins), quite strange
But there are no hazards, you seem to be comfortable with it but I am not, will find out what happened
Strangely again with ZCL it behaves like a normal fork
@holuan , yes 3 addresses becomes bx, you can find them now in the explorer
Thank you for the discussion; these points are all sensible. Closing this for now.
