If its blockchain was the same as bitcoin, then why can't you spend bitcoin on it?
You can.
You're welcome.
No, you can't. Your bitcoin will be lost forever, sent to an address that probably doesn't even have an owner on the bcash blockchain. Your refusal to accept reality is remarkable.
Funny. You seem to be laboring under a misconception. All (OK, 90% of ++) BCH traces its existence to a transaction spending a (pre-fork) BTC UTXO.
Indeed, I have performed this alchemy (over, and over..., and over... ..., and ... ... ...)
Your refusal to accept reality is remarkable.
