Hello thx for reading!
I've checked on
https://www.blocktrail.com/BCC and I found out that I actually own some Bitcoin cash

I own BTC since 2013
as I explained on this unpopular post
https://bitcointalk.org/index.php?topic=2450129.msg25088076#msg25088076 I've already tried to use the bitcoin ABC wallet to import my Bitcoin core wallet to claim BCC's but ended up overwriting my BTC blockchain and had to synchronize the whole thing all over again...
I'm looking for a safe guide to claim it.
Thanks for the help!
