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.
No. It's already been split. You just have to extract the split coins.
Download electron cash and put your seed into there and see if there's anything.
Look at your master public key on a blockchain instead and see if there's any BCC in it.
