Sounds like you lost it.
I've only done a few transactions(sending) since the split. I can't see how it disappeared/lost it? Here is step by step what happened.
1. I had a Electrum wallet since around 2014, I left it this whole time.
2. Before the split, my computer messed up. I felt it was safest to just leave everything until after the split
3. After the split I got a new laptop, with a fresh install of Electrum and I entered the seed for my original wallet(the one containing all my BTC)
4. All of my BTC appeared just fine, I did a few transactions in the following weeks, just sending a few 0.1BTC. Everything is fine here.
5. After reading about the split, I got curious to see if I had BCC available since I held BTC before the split - so I went to Blockchair and typed in my wallet address which contained some BTC.
6. Results on Blockchair said the correct amount of BTC available, but 0(ZERO) BCC available. I thought I was suppose to have both.
7. I came here to start this new thread.
The only thing I can think of is that I have to split it FIRST (move the BTC, then assume the original seed to a BCC compat wallet) then check Blockchair to see that I have both the same amount?
Sorry for any confusion.
