My plan was to buy some fork coin dust from you
I don't follow much Fork news, so I'm not sure if anything changed, but the lack of replay protection may be a problem for BCH/BSV/eCash. The sure solution is to include Fork dust on only that chain in your transaction.
I don't have a working BSV wallet, for the other 2 I can send you Fork dust. I do however have 2 BSV dust private keys, but the wallets are very shitty so sending it is annoying.
At current values, for 105 coins you're looking at $15k-ish in Forks.
It went up:
BCH: $45k
BSV: $8k
eCash: $5k
BTG: $4k
BCD: $100
BCH and BTG can be stored on Ledger. BSV is the worst to deal with, and selling them is a hassle too. Not many exchanges except them, and the few that accept them shouldn't be trusted with much. So send small chunks only to reduce your risk.
I checked my original 3 coin addresses on blockchain.com under
https://www.blockchain.com/explorer/addresses/bch/q[longstrings] which show expected balances and transactions (mined x2, faucet x1, dust in 2021).
I made a watch wallet in Electron Cash using those public addresses. The faucet address shows expected balance but the mined addresses only show the dust balances from 2021.
Meanwhile am syncing
https://bitcoincashnode.org/en/download.html on another installation, should that be needed.
Using the full node and downloading the full chain is probably the easiest solution. Take it offline before entering your private key, create the transaction, and wipe it before ever going online again. It may be tiny compared to the Bitcoins you sold, but still no need risking your money in a hot wallet.
