Hey just to follow up the recent bump: on LoyceV's advice, I spent time in recent days claiming my various BTC forks from a wallet last used in 2014, which means I now own ~0.5 in each of BCH, BSV, BTG and BCHA
If you can tolerate a few hours of tinking with various wallets, it might be well worth your time to follow the advice contained in this thread. Cheers Loyce!
