Sounds good to me.  I give you a private key with about .01 BCH and all other forks, and you give me private keys containing dust for already split BCH/BSV/BCH-A/BTG/BCD so that I can avoid replay?

I had looked at Coinomi.  My one question is that Coinomi creates hierarchical deterministic wallets.  It doesn't import private keys, it sweeps them.  My fear was that sweep would cause issues with the splitting of the unswept keys.  I'm assuming that it doesn't, since I have the private key it's been swept to.  For the coins that it can't deal with, I'd use that initial swept private key to sweep into the other wallets?

In other words, start with the BCH, sweep the keys into Coinomi, send the swept keys to a new address using the dust from an already split BCH.  Next, move on to the other coins Coinomi can deal with and do the same sending with split dust.  After that, use that private key from the initial sweep in Coinomi to sweep into other wallets for the other coins.  Is that basically correct?

So, how do we exchange the private keys?

I've got a few old bitcoin core addresses.  I've moved my bitcoin but not touched any of the other coins.  My plan had been to spend this weekend working on that.  I'm a bit daunted reading up on this, particularly with much of the information I'm finding some time ago.

I'm relatively technically adept.  Coin-wise, I probably only have enough coin to make BCH and BSV make sense, though I'd like to keep my options open for the rest if things change.

I've got an address with just over .01 BCH from before the BCH fork.  I'd be glad to offer up the private key in exchange for some instructions, posted here so everyone can benefit, on how to go about safely recovering the various coins.  I've always handled my bitcoin on a linux commandline system.  I've got access to a raspberry pi, so I can use that, but I don't have an easy way to create VMs.  I also probably don't have enough coins to worry about dealing with offline wallets.  That said, explaining the safe way to do it is appreciated with an understanding that I may do it the unsafe way.

Primarily, I understand there is a replay risk and that I want to be careful about how I claim these coins.  Also, my coins are just private keys, because the bitcoin core wallet isn't a BIP39 wallet.

So, is .01 BCH/BSC/BCH-A worth that writeup?
