Hi George5 and Martisor-Sobru.
If you have used your priv key through electron cash wallet, you probably get scammed.
you can't move your coins but they have a backup of the priv key... so their wallet is really unsecure to use, both for spend/save bcc.
It's a good sign you can see your coins, maybe they can't spend or they forget it.
Hi bitbollo,
I don't think that we got scammed. That software is open-source and many people claim that it worked for them.
Besides, I just checked bcc block explorer and all the coins are still there, on my original addresses.
I start wondering if Electrum wallet gave me the wrong private keys (is that even possible???) when I tried to export them?
Otherwise it doesn't make sense why all BCC wallets say that there is no funds on those keys.
